Questions asked from the app went to Claude alone. Settings › Assistant
now chooses where they open (decided 2026-10-14): Lumo, the default, by
its guest chat with the question in the address's fragment (Lumo's
`prefill`, which needs no account and reaches no server; the address for
one's own account loses the question when nobody is signed in), ChatGPT,
Claude, Mistral, Perplexity, Duck.ai, Grok, Kagi Assistant, HuggingChat,
or an address of one's own with %s. Each link fills the question in for
the person to send (Perplexity answers at once, Grok asks first); Gemini,
which has no such link, and Copilot, whose stopped working, are left out.
The field names the assistant ("Ask Lumo…"). A device that sent questions
to Claude goes on asking an assistant, now Lumo. Connecting Claude to read
studysets stays as it was.

Parity with Japanese's kanji and kana:
- The characters' tab is named by its language (Hanzi, Hangul & Hanja,
Alphabet), its groups too: HSK levels and the characters in common use
(Hong Kong's grades for traditional ones); Hangul and the Hanja taught
in schools; Greek's letters. Radicals for Chinese and Korean in their
own forms (讠 for 言 in simplified Chinese), none for Greek.
- A character's readings are named as its language names them: On and
Kun, Pinyin, Eum and Hun (음, 훈); a letter means its sound and name.
- How characters are written comes by language: Chinese from Make Me a
Hanzi (its medians in KanjiVG's square, Arphic Public License, a data
file beside the app, never in cards), the Hangul letters drawn by the
curator; a Korean word is written letter by letter (닭: ㄷ ㅏ ㄺ). Words
of alphabets (German, Greek) aren't written by hand.
- A Chinese word's pinyin is typed in a session, tone numbers turning
into marks (ni3 → nǐ); KRDict's levels (초급, 중급, 고급) tag Korean
words; a Korean word's pronunciation shows in brackets ([가치]).
- Smaller: Look up in the composer keeps a noun's article; the Watch
filter names its level list; hints and placeholders by language.

Crossing from compact to medium windows or back built screens anew,
losing what they held: a study session started over, a card being
written lost its text, a video began again. The frame around a screen
over the tabs (FramedScreen) was added above it only from medium windows
on, and the snack bars' width (FittedSnackBars) put a Theme above the
app's navigator only there, so the screens below sat at another depth
after the change. The snack bars now always keep their Theme, changing
only the width in it, and the framed screen keeps its screen under a
global key, which moves it whole between the two places.

Animelon's way of learning from video, from the person's own Jellyfin
server: connected per device (Settings, or a studyset's Add material ›
Watch from Jellyfin) with a name and password or a Quick Connect code,
over HTTPS only (plain HTTP only to a server on the same machine); the
token stays in the system's keyring. Shows, films and videos tied to a
studyset follow the person in their settings as the server's and the
item's ids alone (settings schema 9), named by the server when shown.
The Watch screen plays the video (video_player on Android, media_kit's
libmpv on Linux and Windows) with the line in the studyset's front
language cut into the dictionary's words with furigana, and the back
language's line beneath; a word tapped pauses the video and becomes a
card with the line and its translation as its first hint, tagged with
the show. The video's words are listed, most frequent first. The sound is
the track in the studyset's language, whichever the file marks default,
and the menu switches it; the subtitles read are a whole track, never a
forced one (which only covers what the sound doesn't say), and captions
for the hard of hearing only without plain ones. The line and its
translation take the video's width in a box of a fixed height, so the
video keeps its size; in the dark theme the video's colours glow around
it, as YouTube's ambient mode, and the words' panel takes the colour of
the episode's picture under the pointer.
A line is cut into words with one request: DictionaryEndpoint.withKeys
looks up every stretch of it that may be a word, as it stands and as
every word it may be a conjugation of, in the new dictionary_key table
(one row per key, indexed; migration dictionary-keys adds the table and
its index, nothing else), which the loader fills beside the entries.
The instance gets the text of each line looked up and keeps none of it,
as the Watch screen says.
Linux builds need libmpv-dev, and the app links libmpv: the snap stages
Ubuntu's libmpv2, makes the update-alternatives links for BLAS and LAPACK
that ffmpeg's speech recognition needs (staging never runs install
scripts), and removes what the GNOME runtime and core24 already hold, as
older copies of cairo, pango and librsvg hid the runtime's from its GTK.

A source was a book's or an article's parts, however a website or a
video had to be squeezed into them. Adding one to a bibliography or a
step now asks what it is, and its form asks for what cites it: a book
or an article its parts as before; a website the page's link, title,
the site's name, authors and year; a YouTube video its link (checked to
be one), title, channel and year. Websites and videos need their link,
marked as required. A video is cited as APA cites one ("[Video]", a
part of YouTube) and plays in the app where it can, else on YouTube.
The kind is kept in the source's JSON, left out for a book or an
article; a kind this app doesn't know reads as a work. The studyset's
payload goes to schema 6 and a step's to schema 4 for it.

Furigana was the only name for text set above text, though it carries
pinyin, a pronunciation or a translation as well. Its button and dialog
now say furigana in a Japanese studyset, pinyin in a Chinese one, and
text above elsewhere, each with an example of its own: the studyset's
languages reach the core's editors through ContentLanguages, which the
studyset's language scope now sets.
Read-only, the text above shows only under the pointer or after a long
press (another hides it), so the text can be read without it first; its
room stays, so no line moves. While editing, it shows over the pointer
above its dotted text; with the caret inside such text, the button
selects all of it and edits what it has, so it can be seen and changed
without finding its ends.

Dragging it moved the sidebar by each event's step from the width last
built, so whatever arrived between two frames was lost: the sidebar
trailed the pointer, which soon left the 10 dp strip and dropped the
drag. Each move also built every editor of the sidebar anew, its blocks
being a new list on every build. Now the width follows from where the
drag started, the blocks are kept while they stay the same, the handle
is 16 dp with a grip under the pointer, and the resize cursor holds
over the pages while dragging.
The sidebar's share of the room is kept as a device setting once a drag
ends, so every PDF opens with it, in any window.

Flutter's older circular one, as did the spinners in buttons and a few

A studyset opened on its flashcards and slid over to its paths once it
had worked out that one was unfinished, every time it was opened. It now
opens on the tab it was left on, on this device: kept in the person's
folder (studyset_tabs.json), read as their data opens, so at once. The
first time a studyset opens here it still chooses by what it holds
(paths in progress, then flashcards, notes, files), but shows that it is
loading until it knows, rather than one tab and then another; paths that
can't be read count as none.

Text gets a link from the format bar's new link button or with Ctrl+K
(⌘K): the address for the selection, an empty one taking it away, or at
a caret the text as well, written there linked. An address without its
scheme leads to the web. This replaces the editor's own link menu, which
had no button and spoke English only.
Copying and pasting between the app's editors keeps every format: bold,
links, furigana, formulas, callouts, spoilers. The system's clipboard
holds plain text only (the editor's own copy drops the HTML it makes),
so the blocks copied last stay in memory beside it, and a paste takes
them while the clipboard still holds their text; anything else pastes as
plain text, as before, and other apps get plain text. On phones, which
had no way to copy at all, a bar over selected text copies, cuts, pastes
and selects all (the editor's MobileFloatingToolbar), never over a block
taken whole, whose own buttons a tap is for.

A table keeps each row's height on its cells and corrects it after
layout through a transaction, which a read-only editor never applies:
in a path step, a note or a card, a cell of several lines (る, う, つ in
Tae Kim's conjugation tables) ran over its row's borders. Our fork of
the editor now sizes the rows of a read-only table in place, as it
already did the table's height (81c3006c on halkyon/win32-v6; upstream's
main has the same code).

The editor casts a table's sizes (its column width, row height, height,
and each cell's width and height) to decimals, and finds a row's default
height with a null check. JSON written elsewhere may hold whole numbers,
40 where the editor writes 40.0, or no sizes at all: such a table showed
Flutter's error box instead. The Writing System paths in an archive
brought over from elsewhere hold whole numbers. Opening content now gives
its tables their sizes as the editor reads them.

On a phone, a plain band ran behind the floating navigation bar, the
screen's content cut off at its top (your screenshot from the Pixel 9a,
Home's activity card). The bar's whole slot was kept from the screens,
painted in their background: the content stopped above it, as said when
the bar came, until the screens were made ready.
The shell now lets the tab screens run on beneath the bar (extendBody), as
iOS 26's tab bar floats over content. Flutter gives each screen what the
bar covers as the body's bottom padding, and every list of the four tabs
(Home, the library, Explore, Profile) ends with that much room, so its
last item scrolls out from under the bar. Home leaves the Ask field's slot
out while asking is off, as an empty slot would take that room from its
body; with the field, its sections scroll beneath both. A floating button
keeps clear of the system's bar by itself, not of this one: the library's
lifts by what the bar covers (FloatingNavigationBar.coverOf). Inside a
studyset, where the bar steps aside, nothing changes.

Your calls (2026-10-11): a switch per limit, and steps of 5 with any
number typed.
- A daily limit (new cards, reviews; in a studyset's study options and the
study settings) is a switch, "Limit new cards per day", and its number
while on. Counting down to 0 for no limit had to be guessed, and a goal
has nothing like it. Switched off and on again, the limit comes back as
it was; the first time, at the defaults' 20 new cards, or 200 reviews as
Anki starts them. Stored as before: 0 still stands for none.
- The study goal counts in steps of 5 as the limits do (reviews: 25).
Plus and minus go to the next multiple, so 12 steps to 15 or 10, never
below the first step.
- Tapping the number lets any other be typed, from 1 (CountStepper.onTyped).
Pomodoro minutes and cards per round keep their own steps.

A sheet can be busy (SheetScaffold.busy): its close button is off and
greyed, and back does nothing until it ends. The Anki import's sheet is
busy while it imports; before, its close button looked as always and
did nothing.
A studyset's screen, while it imports a PDF or a path, greys its back
button and the path's steps and ignores back: leaving would close the
lists' blocs and cut the import off. Importing a path now says so in its
state, as a PDF's did.

A Pomodoro profile's name could be as long as one liked, and pushed the
Home card's header beyond the window. Of 56 fields, only release notes and
a licence's year had a limit.
Limits by what a field holds (core/widget/text_limits.dart, decided
2026-10-11): a name shown in a menu or on a chip 40 (Pomodoro profiles,
tags, a study button's label); a secondary title or a reading above
characters 60; a title 120 (studysets, notes, paths, steps, PDFs,
callouts, a video's caption, a licence's holder); an answer or item 200
(meanings, readings, glosses, options, categories, gaps, typed answers);
a search 200; a part of a citation 500; a message 2000 (reports, replies,
questions to Claude); a web address 2000; a passage with gaps or a
formula 5000. The public profile and a published studyset's name take the
instance's own limits (display name 30, handle 30, bio 500, links 2000,
name 50), which the app didn't say before. Pasted flashcards to import and
numbers have none. Fields count only from 80 % of their limit.
Text can still be longer where it came from elsewhere (an older app, an
import, a release), so the places showing it cut it short: the Pomodoro
card's header and its profiles. A test shows names beyond every limit on
Home, the library, a studyset's screen with its tabs and topics, the card
browser with its tags, and a session, on a phone and a desktop: none
overflows (it fails on the Pomodoro card as it was).

Deeper studysets, on iOS and Android alike (decided 2026-10-11, after
Material 3's and Apple's guidelines, Android's principles of navigation and
Nielsen Norman Group's on breadcrumbs):
- The screens behind a studyset are its path: below "Japanese › Grammar ›
Tae Kim's Grammar Guide" lie Grammar's screen, then Japanese's, then the
library. A topic at any depth opens with the levels between pushed
beneath it; the path's steps go up by popping to that level's page (they
replaced the location before, so back could skip levels); a studyset
opened from elsewhere gets its levels beneath it. Back, Android's
predictive back, iOS's swipe from the edge and the path all lead one
level up.
- The path's steps are targets 48 dp high; a long press on back lists the
levels above, the nearest first and the library last, as iOS's back
buttons do.
- Below expanded windows the topics open in a sheet from "3 topics ▾" at
the end of the path's line, where Vaia puts "All topics"; no drawer,
whose swipe from the edge is iOS's way back and which Material 3
Expressive deprecates. Topics with topics of their own unfold them, at
any depth, in the sheet and the side column alike.
- The navigation bar steps aside inside a studyset (its screen, notes,
paths and dictionary): Material 3 puts it on the top-level screens and
toolbars below, never both. Apple's guidelines keep the tab bar, lest
people forget where they are; the path, starting at Library, says where.
A strip as high as the system's bar keeps those screens clear of it.
- The bar at the bottom keeps Add material and Study.

bar.

Below medium windows, the navigation bar (Material 3 Expressive's shorter
one) is detached from the window's bottom edge, as iOS 26's tab bar
floats: a rounded bar 16 dp in from the sides and 8 dp above the system's
own bar, at the navigation bar's elevation. Material 3 has no floating
navigation bar for phones, only in its guidelines for headsets.
Around it shows the background of the screen in view: every screen with a
TopGradient claims its background along with its colour (ScreenTint), and
the shell's scaffold takes it, changing as the frame's colour does. The
screens' content stops above the bar; letting it scroll beneath, as iOS
does, would mean padding every screen of the tabs.

The assistant's field now has a switch at its start: a question goes to
Claude or into a web search, and the field remembers which. A web search
opens the chosen engine's results: on Android the device's own web
search by default (ACTION_WEB_SEARCH, answered by its default browser or
search app; Brave Search where nothing answers), elsewhere Brave Search
by default; Settings › Assistant › Search engine offers Ecosia,
DuckDuckGo, Startpage, Qwant, Google, Bing, or one's own address with
%s where the question goes.
Above the field, chips offer what the question is about: a card's
front, back, each hint and its explanation, the studyset's name and
description. None is chosen, so only what the person picks goes along,
each part cut at 600 characters; Claude gets the question and a compact
line per chosen part, a web search the question and the chosen text,
never the studyset's name. A chosen chip alone is enough to send. The
old sentences around every question (where it was asked, the connector)
are gone: they cost tokens for nothing unless the studyset is chosen.

Every screen of a studyset now washes its colour (its own or the nearest
above it), as Vaia does: studying it, its cards, writing a card, its
notes, its paths and steps, its dictionary. The router hands the colour
down from where it resolves the studyset (ScreenColor), so a screen's
TopGradient without a colour of its own takes it.
The dark tone is now a deep shade of the colour, 42 % of it over black
(cerise a maroon like Vaia's #4e0b23, cobalt a navy), instead of a mix
into the background; light mode keeps its tint. The wash reaches about
as far as the header (160 dp; a studyset 180, Home 360). From medium
windows on, the frame fades into the background 60 % of the way down,
and the wash inside its panel is half as strong, as the frame carries
the colour; screens over the tabs (studying, the card browser and
composer, Settings and Connect Claude) sit in the same frame and panel,
without the rail (TintFrame, FramedScreen). The study session's header
lies on the colour with an edge below it, its status bar styled to suit.

Library, Explore, Profile, Settings and Connect Claude now wash cobalt
down from their top as Home does, as far as their header (200 dp);
Home's wash reaches 360 dp, a studyset's 280.
From medium windows on, the window takes the colour of the screen in
view, as Vaia lays it out: the rail sits on it, transparent and without
a divider, and the screen is a rounded panel inset beside it, with its
own wash at the top. The colour is claimed by the screen's TopGradient
while its tab shows and its route is on top (ScreenTint), so the rail
turns maroon beside a cerise studyset and back to cobalt on leaving it,
in a quarter of a second. The frame is as strong as the rail's labels
allow (WCAG AA on onSurfaceVariant, every palette colour, light and
dark), weaker towards the foot.
Two things the panel's 24 dp less room brought out: a long description
was laid out whole for its first frame, before it was measured, and
overflowed a shorter column; it is now laid out whole but shown no
taller than its preview from the start. And between 840 and about 960 dp
of screen, a studyset's app bar (Study, Add material, Share, options)
didn't fit; Add material is an icon there, its label in the tooltip.

(the person's learning on the instance, a studyset by name, or the studied
card's front and back as text), cut at 12,000 characters, for the person
to read and send in Claude. A Claude plan can't drive a chat inside
another app, as Anthropic allows no third party to offer sign-in with it;
Claude is to read the studysets through a connector on the instance
instead (next). Nothing leaves the app until the person sends it there.

Home starts in cobalt and a studyset's screen in its colour, its own or the
nearest above it (cobalt where none has one), fading into the background
below the app bar, which stays clear above it. The top tone is 60 % of
the colour in dark mode (cobalt a navy, cerise a maroon) and 35 % in light
mode (a pastel tint), less where the theme's text would fall below WCAG AA
on it; a test holds every palette colour to that in both modes. The
status bar's icons follow the tone. Content stays below the app bar, so
nothing scrolls under its title.

Choosing a destination in the navigation bar or rail plays the platform's
lightest haptic, the selection click (a clock tick on Android), as a
short, weak confirmation. It follows the system's touch feedback setting
and does nothing where the device has no motor.

A new install asks first which instance to keep the person's studysets
on, as Mastodon's apps do: an address, checked to answer as an instance
of Halkyon Learn, or the build's own (learn.halkyon.eu) in one tap.
Nothing is made anywhere before that, not even an anonymous account. An
install from before goes on with the build's instance without asking.
As Moshidon does, the device keeps an account on each instance it was
used with, each signed in with its own folder and session, one in use at
a time. Settings › Switch account lists them: another one switches at
once, anonymous accounts included; Add account chooses another instance;
removing one not in use deletes what the device holds of it. Signing out
ends only the account in use.
The build's own instance keeps its data where installs kept it before
(`people/`, Serverpod's own session key), so they keep everything; other
instances get folders and keys of their own. What the device shares
across instances (its settings, sounds, the Pomodoro timer's place in the
system) is made once and outlives every switch.
The F-Droid listing drops TetheredNet: the app is no longer tied to the
project's instance.

The Sync card in Settings says how many changes made on this device
haven't reached the server yet: "3 changes wait to sync", in place of
"Everything synced" until a sync takes them, and beside a failure.
The sync engine can't tell, since the server only says what it has at
the start of each sync, so the app counts: every save asks for a sync,
and a sync that goes through takes the saves made before it started.
The count is kept in the person's folder, so it outlives the app.

Each card's foot now says who made the studyset: "By you", or for a copy
of a published studyset its author's handle. Beside the star, a lock or a
globe says whether it is out on Explore, and opens the Publish sheet.
The instance says which of the person's studysets are published and not
withdrawn (`PublishEndpoint.published`, additive: older apps don't call
it), and the app remembers that in the person's folder, so the library
shows it offline too; publishing, withdrawing and looking one up keep it
current.

Stage 4 of the public tier (ADR 0005, rule 6), its server and the app's
data. A learner writes a report or a suggestion on a published studyset,
a card, note or step of it, in their own synced space, so it works
offline; replies and the author's decisions (closed, hidden, accepted,
declined) likewise, in the writer's or the author's space. The instance
gathers them: public to everyone signed in, but for what the author
hides; for the author's inbox and the writer's. What counts is decided
as rows are read, since a modified app could write anything: threads
from people with an identity and a public profile the author hasn't
blocked, replies from the writer and the author alone, decisions from
the author alone, no suggestion under "no derivatives". The author gets
the files a suggestion names from its writer's, and the next release
credits the writers of the suggestions accepted since the last
(Co-authored-by). Deleting a person deletes their blocks and what they
read; what they wrote goes with their space.
In the app, the repository writes reports and suggestions (a card, note
or step as the learner has it, without what is theirs alone, with the
files it names) and takes an accepted suggestion into the author's own
card, note or step.

A copy's top studyset says when a newer release of what it came from is
out, and what it would bring: changed, new and withdrawn items, counted
against the release the copy last took. Update takes it, never by
itself (ADR 0005, rule 4): cards, notes and steps take the release as a
revision on the one where they last took a release and merge per side,
as a dictionary's corrections do, so what the learner changed stays and
a side both changed is a conflict to settle; studysets, paths and PDFs
take each field the learner left as it was. New items come in where
they belong, unless the learner deleted that part; what the author
withdrew stays, marked, and the card browser filters for it; what the
learner deleted stays deleted; progress is never touched.
The instance gives out any release by its version, for the app to
compare the two. UpdateTaken moves into the shared revision merge, now
that notes and steps take updates too.

Explore lists what is published on the instance as the old app's feed:
search over titles and authors, filters for languages and kinds of
content, the newest release first, the next page only when asked for;
each studyset opens a summary with all of it. Anonymous people explore
too.
Add to library makes a copy in the app, as an import: through the
person's own repositories, the files among their own files, the tags by
name among their own tags, everything read first, so a release in a
schema this app doesn't know is refused whole. The server never writes
into a learner's space. Every item of a copy names where it came from
(publication, item, release: card schema 9, note 3, step 3, path 2,
PDF 2, studyset 5), merged per side like the rest, for later releases to
be taken from there.
The Publish sheet takes a studyset off Explore again, after asking.

A person with an identity and a public profile publishes a studyset with
everything inside it as its next release (ADR 0005, rule 3): the server
reads their synced rows and writes them through the git command as a
commit on main and the annotated tag vN, in a bare repository of the
studyset's own, named by a random public id made at the first publish.
A release is a directory per studyset with a file per card, note, path,
step and PDF (its id, position, tag names and payload as synced, keys
sorted and indented) and the files the content names, without what is
only the author's (a card's report, a PDF's deadline). Publishing is
refused without a licence allowing passing it on in every studyset ("no
derivatives" allowed), with revisions to settle, with files not uploaded
yet, when nothing changed, or for a name that won't do; the name is
fixed from the first release, as is the person's handle.
In the app, Share in a studyset's action row opens the Publish sheet;
publishing syncs first, and settles by itself the revisions that merge
cleanly, listing only real conflicts. The server's image gets git, the
repositories a volume of their own, and the hourly backup a git bundle of
each.

Stage 1 of the public tier (ADR 0005). A person with an identity has a
public profile: a handle by Mastodon's rules (1 to 30 letters, digits or
underscores, unique whatever its case, a few kept for the instance),
changeable until they first publish, on the instance's account domain
(ACCOUNT_DOMAIN, else the server's host; the instance info names it), so
`raisondetredev@halkyon.eu`; a display name, a bio, up to four links and
an avatar. The table is server only: the app gets a Profile without the
person's id. ProfileEndpoint (identified only) reads, saves and removes
the caller's own; ProfilesEndpoint finds anyone's by handle.
An avatar is a PNG of at most 1 MB that the app draws anew from the
picture chosen, its middle square at 400 pixels, so a photo's metadata
never leaves the device. The server keeps it in the public storage named
by its content, so its URL tells nothing about whose it is, and deletes it
once no profile shows it. Deleting a person deletes their profile and its
picture.
In the app, the Profile tab holds the profile as a form, laid out as the
old app's; anonymous people are told GitHub sign-in gives them one.
Migration 20261009184924904-public-profiles creates public_profile with a
unique index on the person and one on the handle in lower case; it touches
no other table, and the old server never sees it.

- Reorder: rows from before an order existed all share one position, and
one moved among them landed at their end; the run it goes into now
gets positions of its own (placeAmong), for notes, files, paths,
steps and sub-studysets. Rows whose deletion can still be undone count
for nothing, as the list leaves them out, and a dropped row takes its
place at once instead of snapping back until the order is read again.
- Export: two studysets inside each other (moved so on two devices
offline) no longer make it run forever; links to files whose names
hold #, % or brackets work; PDFs, images and sounds go into the zip
without being compressed again; any error says the export failed.
- Text import: a real CSV reader (quoted fields over several lines, a
back over several quoted fields, a stray quote spoiling only its own
line), the separator guessed from the text (semicolons from German
spreadsheets), and files in UTF-16 or Windows-1252 read as meant.
- A tab whose notes, paths or files couldn't be read says so rather than
"No … yet"; an Anki import from the Library that fails leaves no empty
studyset behind.

Furigana:
- Text typed after a word with a reading no longer takes the reading.
- A reading over text formatted in parts (a bold kanji) is drawn once,
over all of it, each part in its own style; in Markdown it is one
<ruby>, the parts keeping their marks, the reading escaped.
- Readings follow the editor's text size, not the system's, and a
linked word with a reading still opens its link.
- Anki's <ruby> keeps the formatting inside it.
- The Markdown export escapes what Markdown would read as its syntax
and keeps blank lines inside code blocks.
Typing a reading:
- Hepburn as learners type it: onna is おんな, konnichiwa こんにちは, m
before b, p and m is ん (shimbun); keyboards' n' and nnn still work.
- The caret stays where the person types, also in the middle.
- Macrons count both ways (ō as おう or おお); a card listing several
readings (いく、ゆく) takes any of them; only words written with kanji
ask for their reading.
- No autocorrect, suggestions or curly quotes in the field; Done with
nothing typed keeps the keyboard; the lock screen lets go of the field.

Text within a line can carry its reading now (`ruby` on the text's
attributes, `かんじ` on `漢字`), word by word, in lessons, example
sentences, notes and cards alike. Shown, the reading sits above the text,
smaller and centred, the text level with the line around it; while
editing, the text is dotted underneath and the caret moves through it as
text, as with formulas. The format bar's Furigana asks for the reading of
the text selected, starting from the one it has, and takes it away.
An Anki field's `<ruby>` keeps its reading as furigana now, each base its
own, instead of "漢(かん)"; Anki's `漢字[かんじ]` stays as written, as
telling it apart from other brackets is guesswork. The Markdown export
writes furigana as HTML's `<ruby>漢字<rt>かんじ</rt></ruby>`.

The studyset sheet gains Languages, as before: off until "Set
languages", then the language of the cards' fronts and of their backs
(22 languages, Chinese in its two scripts). A studyset without its own
takes those of the nearest studyset above it, both together; set for the
first time, they start from those it took. The payload held both fields
already.
They set its text: Noto Sans SC, TC and KR join Noto Sans JP (bundled,
never fetched; 34 MB more, fonts 42 MB in all, your call), and since
Han characters take the shapes of the first font that has them, every
screen inside a studyset (its screen, cards, notes, paths, studying it)
puts the font of its front's language first, else of its back's,
Japanese otherwise. Every studyset route goes through one helper now.

The app brought no fonts: text took each device's own, a minimal Linux
showed Japanese as boxes, and kanji could take Chinese shapes. Now Noto
Sans is the app's font everywhere (Latin, Greek with polytonic,
Cyrillic), and Noto Sans JP fills in kana and kanji in their Japanese
shapes. Noto Sans JP alone wouldn't do: it lacks accented and polytonic
Greek. Both come with the app and are never fetched; scripts neither
covers fall back to the device's own fonts.
Each family is one variable font holding every weight (Flutter sets the
weight axis from the requested weight; a test checks bold inks more):
0.7 MB Noto Sans, 0.7 MB its italic, 8.1 MB Noto Sans JP, from Noto's own
GitHub releases (assets/fonts/ATTRIBUTION.md). Their SIL Open Font
License texts join the app's licence list.

With two notes or more, Reorder beside the tabs gives each note a grip
in place of its options, as paths have, until Done; e.g. to follow a
reading order. A note's position was stored already; the repository
now moves it (only that column changes, and it syncs).
The notes' bloc sits with the studyset's other lists now, above the

Export content, in the studyset's options, writes the studyset and
everything inside it as one readable Markdown document (decided
2026-10-08: no re-importable archive before the public tier's release
files): its title, secondary title, description and licence, then its
flashcards (answers below their questions, choices as task lists),
notes, learning paths (steps with their kinds, answers, feedback and
sources), PDFs and bibliography, then each sub-studyset a level deeper.
Rich text keeps its formatting; formulas go between dollars, callouts
become quotes, spoilers HTML details, YouTube videos links. With files
(images, sounds, PDFs) it keeps a .zip of the document and them under
files/; a file this device can't have is named and counted.
Saving goes through a FileSaver: file_selector's dialog on the desktop,
file_picker's (Android's Storage Access Framework) on phones, a direct
dependency now at the version the editor already brings.

The read-only view passed its alignment to the text alone, which the
editor lays out only as wide as itself, so a centred face stayed at the

an alignment chosen in the format bar wins.

The Study pill reads "Learn 12 flashcards" in the app bar and "Learn 12"
floating, "Study" with nothing due, and is off with nothing to study,
saying so. With a path not finished, a chevron beside it offers to start
or continue the path: a menu in the app bar, a Study mode sheet on
phones. The floating bar rises above the licence line, which takes two
lines at most.
Add material offers a path, flashcards, a note and a PDF, in that order;
imports moved to the options' Import content, which asks for a learning
path or an Anki deck. The options read Edit, Move, Study options, Import
content, Reset progress, Archive, Delete. The bibliography is an outlined
round button above the content, and on phones at the foot of the topics.

empty tab says so in its middle; tapping the open tab again returns to

a fixed height, measured, with Read more opening it whole under the

what it holds ("Empty" with nothing, files counted too), and its options

A studyset's notes and learning paths are routes of the Library tab, as
its screen is, so the navigation stays beside them; studying, cards, PDFs

the edge again and again. The sync trouble dot shows on the Settings cogs

The header's Undo takes back ratings, burials and deletions, last first,
across the session's rounds and from the end of a round, and shows the
card again. A card deleted during a session is held (DelayedDeletions.hold)
