Why black and white is made with Ghostscript and how close it is to what Elmer prints; why Print image goes through the engine's copy image, with the table of what each other way failed on; what it cannot reach (a CSS background picture) and what it costs (the clipboard lives in Wonder Ink afterwards). The manual says Print page and Print image, and that the preview turns grey. Sunday's paper checks for both, in testing.md. Co-Authored-By: Claude Opus 5.5 <[email protected]>

# 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 or 0.2.6.3**: 0.2.6.2 is limited to picture printing,
|
||
the Presentations memory failure and the settings lockdown, and 0.2.6.3
|
||
to the black-and-white preview and Print image. 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`).
|
||
- **Linked lesson text opens an intermediate popup** instead of following
|
||
the link, where Chrome follows it directly. Investigate: probably a
|
||
site script choosing `window.open` for a gesture Wonder Ink reports
|
||
differently, or `createWindow` being asked for a popup type we treat as
|
||
a tab.
|
||
- **Session retention.** Today closing Wonder Ink signs the teacher out
|
||
(session-only cookies). Wanted: recover from an accidental close, but
|
||
expire after a configurable period of inactivity, including across
|
||
restarts. Needs a design that never leaves one teacher signed in for
|
||
the next — and first, a real account to measure where the site keeps
|
||
its sign-in: 0.2.6.1 found cookies do clear on close, but the profile's
|
||
Local Storage persists, and whether the site stores its token there has
|
||
never been tested.
|
||
- **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.
