Changelog — tabs, restore, load busy (1.5.5 → 1.5.12)

Product: 1.5.12

Cache-bust: app/config.js → 1.5.12-redact-save-howto

Date: 2026-08-16

A pile of "why is my tab blank / why did I save half a PDF" fixes, plus a real redact tool and a save that comes back as the file. Packaging/SVC untouched.

1.5.12 — Redact, save bounce-back, how-to

• Redact tool (D): click or drag over PDF text (or a blank/scan region) and drop black cover bars. Per-line if you lasso a paragraph. Not certified redaction — visual cover until Save PDF.
• Bars stay quiet on create (no toolbar in your face). Click one later while still on Redact to move/recolor.
• Save Project: after write, reopen the .gapdf into the same tab (Chromium/PWA handle; Firefox uses the blob we just built). If reopen fails, the working tab stays put.
• How-to: dev/HOW-TO.md + in-app app/howto.html (linked from ?). tools/sync-version.ps1 stamps VERSION → config/README and re-renders DOCs/.
• Cache-bust: 1.5.12-redact-save-howto.

TL;DR (if you're skimming)

• Click-to-redact (D), save-project reopens the file you just wrote, in-app how-to.
• Multi-file combine: dim + block save until done (no half-sandwich exports).
• Big single PDF: pages stream in, soft toast, save/print wait — no disco dim.
• Session restore: freeze-before-open, soft toast, no blank ghost tabs.
• Spare empty shell = secret canvas, not a fake tab.
• Close active tab → focus right, else left (not "Map.first = blank").
• Multi-drop actually gets all the files (Chromium DataTransferItem gotcha).

1.5.11 — Tab close focus

Right neighbor first, else left. Old code grabbed Map.first → often a hidden spare → blank until click.

1.5.10 — Spare shell hidden

Internal empty pane for the DOM. Not a tab while real docs exist. + still makes a real Untitled.

1.5.9 — Empty shell cleanup

Hard-refresh was leaving a blank tab buddy. Spares + don't persist empties.

1.5.8 — Restore soft status

Restore bar uses toast + gate, not full-screen dim.

1.5.7 — Soft doc gate

Multi-page open: watch pages roll in; save/print gated; 30min panic timeout; forceClearAppBusy().

1.5.6–1.5.5 — Load / restore / multi-drop

Startup open vs restore race fixed; restore de-dupe; Chromium multi-drop fix; multi-file dim+busy.
