+## Decisions after trying 0.1.0 on a phone (3 Nov 2026, the developer's)
+
+The developer's review of 3 Nov 2026, with Todoist's screens beside Todo's; the project
+label at a row's end the developer's answer (right-aligned, as Todoist's, over left after
+the date), the rest the developer's asks, carried out as described.
+
+- **D19 Today and its tabs' icons**: Today's tab shows today's day of the month inside a
+  blank calendar, as Lucide's `calendar-1` holds a 1, drawn again at midnight
+  (`TodayIcon`); Browse is Lucide's `menu`, Display's button `square-menu`. **Today has at
+  most two groups**: what is overdue, folding under its heading (its chevron, beside
+  Reschedule; the fold not kept), and today's, headed by the day alone. **A day's heading**
+  reads as Todoist's, "Tuesday, 3 Nov" ("Dienstag, 3. Nov.", the pattern a text of each
+  language, `dayHeadingPattern`); Upcoming's days keep "· Tomorrow" where it helps, Today's
+  has no "· Today". Upcoming's way back to today shows whenever another day than today is
+  picked, not only off this week.
+- **D20 Rows in rounded boxes, a list's rows a group** (as Todoist's): each row its own
+  surface (`TaskTile`'s box, `TaskRowPosition`, `taskGroup`), rounded at the group's ends
+  and slightly at the joins, so a chosen row's colour stays inside it as the list scrolls
+  under a pinned heading (it showed under Upcoming's week strip, as the row's tile was
+  painted on the screen's surface below the list). Its project and section end the line
+  of its date at the row's right edge.
+- **D21 Lists pulled down sync now**, as Learn's: Today, Upcoming's agenda, the Inbox and
+  every project (`TaskRefresh`, halkyon_ui's `AppRefreshIndicator` over halkyon_app's
+  `syncAndWait`), an empty list too (`PullRoom`). A board's columns and the 3-day grid
+  don't, as they scroll sideways or both ways. **A project's screens wash in its own
+  colour**, as a studyset's in Learn; one without keeps Todo's strawberry.
+- **D22 Display as Todoist's**: each layout a phone's outline with its picture, its name
+  below on one line, a radio button marking the one in use; the rest in rounded groups
+  under plain headings. "Add section" in place of "New section".
+- **D23 Quick add a small bar docked above the keyboard** (amends D8, D15): the title,
+  then one row of boxed buttons (+ for the description and deadline, the date, the
+  priority, the labels, the project), each its icon alone until something is set, and a
+  send button, the list in view behind a lighter barrier. Its buttons show from the
+  start (D15 had its chips come with the first letter), as Todoist's bar has them. Where
+  sheets are dialogs, the same bar in a dialog.
+- **D24 A task's sheet partway up, its parts in rounded boxes** (amends D13): on a phone
+  it opens as high as its content, at most 65 % of the window, and is dragged up to the
+  whole window or down to close (`DraggableScrollableSheet`); the title, description,
+  date and reminders each a box, the priority, labels, deadline and project a row of
+  chips (named while unset), the sub-tasks a box ending in Add sub-task. No principle of
+  the project's argues against Todoist's layout: grouped rounded boxes are what the
+  review asks for across the apps. Todo keeps no comments, so there is no comment field.
+- **D25 Explanations one tap away**: what a setting does stands behind halkyon_ui's
+  `HelpButton` beside its name (`TitleWithHelp`), not always below it, in Todo and
+  Meditate; what is the person's own (a value) stays in view, as do an empty list's
+  message and quick add's hint while words are highlighted.
