A window snapped to half the screen (640-800 px) or a 1366x768 laptop
at 150 % (911 px) got the phone and tablet layout: bottom tab bar,
folders in a drawer, Settings as a phone list with a Back arrow. The
layout switched at the 64rem (1024 px) breakpoint.
Now the phone layout starts below 600 px. From 600 to 1024 px the app
is a compact desktop: app rail at the side, folder sidebar folded to
its icons (the existing collapsed state, opened per session with its
toggle), Settings with its two panes and a narrower page list. Below
840 px the split layout opens a message in the list's place, as the
focused layout does. This holds in the browser and the desktop app,
in the Pro shell (which now runs from 600 px) and under Mountain View.
- `hooks/use-media-query.ts`: classifyWidth, PHONE_BELOW 600,
FULL_DESKTOP 1024; the tablet class (`isTablet`) is gone, the store
has `isCompact` instead. Plugins still see "tablet" for it.
- `app/globals.css`: a `desk:` breakpoint at 37.5rem for the layout
classes, and a `tap:` variant for 44px rows on phones and touch
screens below 1024 px (was every window below 1024 px).
- Touch screens below 1024 px keep swiping list rows (was phones only).
- The boot skeletons, boot script, mail app, sidebar, reader, admin
shell and calendar, contacts and files follow the new widths.
Tests changed with the behaviour: the tablet cases in pro-gate,
mail-app-mv-composer-move, mail-app-compose-handoff,
mail-app-thread-expand-mark-read, mobile-tour-end and
thread-list-item-columns now run on a phone or a compact desktop, as
those widths no longer exist as a tablet. mail-app-short-window-tab-bar
is replaced by mail-app-compact-layout: a phone on its side is a
compact desktop with the rail at the side, so the short-window tab bar
rule is gone. Class and media-query assertions follow desk:/tap: and
37.5rem; the 32px-text test uses 1100 px, since 1440 px at 32px is now
a compact desktop.
The admin skeleton test and the outgoing-hosts path test now expect the
sidebar heading "Users" and the page "Features and settings": the
Organisation group was renamed and User policy moved into it.
Offline sat in the middle of Backup & reset, privacy settings were spread
over Reading, Composing and Message list, and the version card took room
from the page list in the sidebar's footer. The search matched letters
inside words ("lock" found Time format and Send Checks) and knew no other
words for a setting ("offline", "autoreply", "logout" found nothing).
- Offline is a page in the top group: Keep mail on this device, what is
kept, Remove everything from this device, and the Outbox as its own
section. Old `/settings/backup/offline` links and the offline notice
land there.
- Privacy holds remote images and trusted senders, read receipts, sender
pictures from the web, the desktop app's usage info and crash reports,
and a link to the push relay on Notifications. Reading, Composing and
Message list keep a link row; old links to those sections land on
Privacy.
- About is the last page and holds the version card; the footer keeps the
Advanced switch.
- The search matches whole words and word starts (substrings only in
Chinese, Japanese and Thai), and each row can carry synonyms in the
user's language. A page matches by its name and keywords or when one of
its rows has every word. Account gets a Sign out row so "logout" leads
somewhere.
- The index test now also fails when a page draws a section the index
doesn't know, and a new test fails on two indexed rows with the same
name. Tests that rendered remote content and sender pictures on Reading
and Message list render Privacy instead, since that's where the rows are.
The desktop app and an installed PWA had a row across the whole window
with the title and the window controls. That row is gone. The rail,
sidebar, list and reader run to the top of the window in their own
colours, and the controls sit in the top row of whatever is rightmost.
- `lib/window-controls-overlay.ts` finds and marks those rows before
paint, and they reserve the controls' width through
`--titlebar-right-inset`
- the rows and the rail are the drag area, everything clickable is
`no-drag`, and an invisible band lets a page with no row still move
- settings and the admin shell get a row only under the overlay, Pro's
tab strip and Mountain View's bar match the controls' height
- Alt floats the menu over the top left, in `window-menu-bar.tsx`
- skeletons carry the same marks, so nothing shifts when the app loads
An installed app had no title bar of its own, no way to save attachments
except a zip, and "pop out" stayed inside the page. A new window was a
second copy of the app that had to restore the session itself, and on
start-up that evicts any login made without "Remember me" from the list
every window shares.
- Title bar: `display_override` with `window-controls-overlay`, one
`--titlebar-inset` variable at the page roots and skeletons, and a drag
strip with the window title. 0 without an overlay, so nothing moves.
- Save all to a folder: `showDirectoryPicker`, asking the device policy
before the picker and before each file, with the zip as the fallback.
- Pop-out routes `/popout/message/<id>` and `/popout/compose`, on offer in
an installed app or when the desktop bridge has windows. Hidden in Lite.
- A pop-out borrows the main window's session and never evicts or starts a
token timer. Every renewal now takes a Web Lock, so two windows can't
send the same refresh token, which Stalwart 1.0 may treat as a replay.
- A draft moves to its window under the same id. A closing window hands
unsaved text to the main window to save, since its own request wouldn't
survive the close.
- Read state, drafts, theme and language follow across windows, and
`html[data-desktop]` gates the app-like behaviour in `app/desktop.css`.
