# Backlog — 0.3.0 and later

Recorded after hands-on testing of 0.2.6.1 in September 2026. **None of
this is in 0.2.6.2 to 0.2.6.4**: 0.2.6.2 is limited to picture printing,
the Presentations memory failure and the settings lockdown, 0.2.6.3 to
the black-and-white preview and Print image, and 0.2.6.4 to temporary
workspace restore (the two items that were here about links and sign-in
retention are answered in wonder-ink.md). Each item says what was
observed, so whoever picks it up starts from the evidence.

## Wonder Ink

- **An interface like Chrome's, visibly the classroom's.** Familiar tabs
  and back/forward/reload, without an address bar, new-tab button or
  anything that takes a teacher somewhere the lesson did not. The 0.2.6.1
  tab strip is a step towards it, not the design.
- **The PDF viewer's own Download button.** It saves a copy, which the
  download handler then opens as another worksheet tab. Remove it, or
  intercept the download from a worksheet tab so it does nothing visible.
  (0.2.2 already skips re-opening a save from a worksheet tab — see
  `from_worksheet` in `on_download` — so check first which route it now
  takes.)
- **One Print, not two.** A worksheet tab has the viewer's printer icon
  and Wonder Ink's Print; both now open the same preview, but a teacher
  sees two buttons. One teacher-facing workflow.
- **Readable worksheet names.** Tabs show the downloaded file's name,
  which for many worksheets is a long generated prefix. Strip it, or take
  the name from the PDF's own title.
- **Print image and CSS background pictures** (from 0.2.6.3). The engine's
  hit test does not call a CSS background a picture, so right-click there
  offers only Print page. Only worth doing if Sunday's testing finds
  Wonder Ink's site draws artwork that way; the lab has no account to
  tell. See wonder-ink.md, *Print image*.
- **The clipboard after Print image** (from 0.2.6.3). It is put back, but
  owned by Wonder Ink afterwards, so text copied elsewhere before is gone
  once Wonder Ink closes — there is no clipboard manager in the session.
  Measured, and judged smaller than leaving the picture there.
- **A speaker on the tab that is playing sound** (`QWebEnginePage.recentlyAudible`).
- **A picture in its own tab, in a room above 100%** (seen testing
  0.2.6.4). Page zoom is the room's `UI_SCALE`, and the engine's picture
  viewer takes it too, so at 200% a slide opened from a lesson is shown
  twice its size with scrollbars rather than fitted to the window, as
  Chrome shows it. Printing is unaffected.
- **Staying signed in, if WonderInk ever issues a real session token.**
  Today its sign-in is the teacher's email and password in a Basic-auth
  cookie (measured, 0.2.6.4), so keeping it would mean keeping a password;
  Wonder Ink does not. Worth asking WonderInk for a server-issued token
  that can be revoked; until then, closing Wonder Ink signs the teacher
  out, and only the recent tabs come back.
- **Workspace time as a room setting**, if two hours turns out wrong for
  some room: `IDLE_LIMIT_SECONDS` in `classroom_wonderink_workspace.py` is
  the one place, and a device.conf key would be a small change.
- **The site's sluggishness, where it is ours.** Measured in 0.2.6.1:
  Wonder Ink and Chrome take the same time (about 2.9 s cold) and the
  site is the weight — 119 – 160 requests, 3.2 MB, the Google Maps API
  loaded twice. Ours to look at: whether a classroom's QtWebEngine has its
  GPU (`classroom-wonderink --diagnose` on the machines), and the page
  shell being revalidated on every warm load (62 – 87 ms).
- **The browser is scaled twice** under Plasma (dpr 2.25 at 150%):
  `classroom-browser` forces `UI_SCALE` on a Chrome that already follows
  the compositor. Deliberately left in 0.2.6.x because teachers know that
  size, and Wonder Ink was matched to it. Decide once, for both.

## Presentations

- **A normal, maximisable application** instead of the small floating
  library window.
- **Consistently sized tiles in a responsive grid.**
- **No unnecessary internal scrollbars or stretched layouts.** 0.2.6.2
  had to give a row extra height by hand when a card carries the
  memory-failure message; the layout should size to its cards.
- **Keep the window's size and position** when importing a presentation
  or changing a cover.
- **Click the slide to advance.**
- **Hide the pointer after a moment of stillness while presenting**, and
  bring it back on movement.
- **Keep the keyboard controls**, and never advance when a playback
  control itself is clicked.
- **Remote control of a presentation** — later than 0.3.0.

## The launcher and Parent Call

- **Remove the subtitles under DVD and Presentations** on the launcher.
- **Parent Call appears among the ordinary applications for a moment and
  then disappears**, which looks like a crash. Keep it reachable through
  its background or notification route without it flashing up as a
  window.

## The settings lockdown

- A notification's **Configure** button still shows, and opens a small
  "module disabled" window (0.2.6.2). Hiding it needs a change to Plasma's
  notification applet, not configuration — revisit if Plasma gains a
  Kiosk key for it.
- The settings-module list is per Plasma release. `tools/lab/converged-check`
  fails when a new one appears; the list in `config/plasma/xdg/kdeglobals`
  then needs the new name.
