Two problems the old editor kept hitting:
- __pending drain race: opening the editor a second time (refresh, back-and-
forth navigation) found the storage entry already consumed and bailed to
a blank canvas silently.
- Cross-origin img loading: editor.html at file:///…/addons/screenshot/
loading a scratch PNG at file:///…/addons-data/ counts as cross-origin
under Chromium's file-URL policy; setting crossOrigin="anonymous" made
the load fail outright.
Rebuilt editor v2:
- Load path is idempotent: silentmode.invoke("getBytes", {name}) → addon
reads the scratch file and returns a data URL. No __pending drain, no
cross-origin trickery — data: URLs are same-origin and never taint the
canvas, so getImageData / toBlob keep working.
- Two-canvas model (#base + #over, over is pointer-events:none) so live
previews don't cost a full re-composite per mousemove.
- Tools: cursor, arrow, rect, ellipse, pen, text. 6 swatches, 3 widths,
undo / redo (25-deep). Copy + Save at the top bar. Back and Maximize
buttons in the same top bar so navigation controls stay reachable when
the toolbar wraps at narrow widths.
- Keyboard: A/R/O/P/T select tool, Esc = cursor, Ctrl+Z/Shift+Z undo/redo,
Ctrl+S save, Ctrl+C copy.
- Toast surface for save/copy/error feedback.
Sidebar panel gains a direct raw-save path so the user can copy or save the
capture without entering the editor:
- Two-row actions: [Copy] [Save] on top, [Discard] [Edit] below.
- Copy uses navigator.clipboard.write(ClipboardItem); Save uses
<a download> with a Blob URL — same path Chromium's will-download
tracker already handles, so the file lands in Downloads and the chip
updates like any other save.
Inline "clear all" confirmation replaces the native confirm() — the old
system-modal opened over the tab area (out of the sidebar's visual
context) and looked like Windows 95. Now a compact red strip appears
under the Recent header with Cancel / Delete buttons.
Sounds + a sound-on/off toggle in both surfaces:
- Web Audio oscillator-synthesized (no .wav shipped): shutter click on
capture, two-tone bloop on copy, descending pair on discard/back,
ascending triad on save.
- Preference stored in silentmode.storage under "soundOn" (default on),
shared between the panel and the editor.
Simplifications:
- Dropped the addon's "arm" onMessage handler (superseded by getBytes).
- Manifest capabilities: sidebar-panel + capture-tab (no open-tab,
no toolbar-menu).
Bundled but not shipped — parent session handles the OTA sign + push.
