Settings saved in the panel are written to data/settings.json and
overlaid onto process.env, taking precedence over environment
variables and applying immediately without restart. Enable by setting
ADMIN_PASSWORD; on serverless platforms without persistent disk the
panel degrades to read-only.
PR #840 fixed issue #815 in the Electron main process via
will-prevent-unload + preventDefault. The renderer-side workarounds
introduced by previous fix attempts (#642, #648) are no longer needed
and never had effect for their stated purpose.
Removed:
- configuration={ confirmExit: false } in DrawIoEmbed
confirmExit is not a recognized draw.io config key (zero matches in
jgraph/drawio source). This was always dead code.
- modified=0 / keepmodified=0 URL parameters
Per drawio source (app.min.js:14898), these only suppress the
post-save modified-flag clearing — they do not prevent edits from
setting editor.modified=true. They were ineffective for blocking
beforeunload prompts and actually prevented draw.io from clearing
its modified flag after save.
- canPersist / canPersistChecked state and isIndexedDBUsable() probe
Their only purpose was gating the dead config above. Removing them
also removes a startup delay before the iframe renders.
- handleDrawioAutoSave wrapper
After PR #780 stripped its body, it was a pure passthrough useCallback.
Now passes handleDiagramAutoSave directly to onAutoSave.
- withDB / isClosingError / resetDBPromise / onversionchange / onclose
/ terminated handlers in lib/session-storage.ts and lib/template-storage.ts
PR #648 added these to recover from 'IDBDatabase: connection is closing'
errors that PR #642's first land caused via db.close() on the shared
singleton. That bug was already fixed in c5de1a1 (re-land of #642),
three minutes before PR #648 commits started. The retry handlers
defend against multi-tab / version-change scenarios that cannot occur
in this single-instance Electron app (requestSingleInstanceLock).
template-storage.ts copied the same pattern when introduced by #773.
Verified:
- npx tsc --noEmit passes
- Manual test in dev mode: session save/load works, template create works,
diagram-only persistence works.
* feat: add all Draw.io themes to settings panel
Add all available Draw.io themes (kennedy, atlas, dark, min, sketch, simple)
to the settings panel dropdown. Previously only min and sketch were available
as a toggle button.
Changes:
- Replace the Draw.io style toggle button with a dropdown selector
- Expand theme type from "min" | "sketch" to include all 6 themes
- Update localStorage validation to accept all themes
- Update handler from toggle to direct theme selection
Closes#499
* fix: localize theme labels, tighten DrawioTheme typing, sync dark param
- Move DRAWIO_THEMES + DrawioTheme to lib/drawio-themes.ts; reuse in
page.tsx, chat-panel.tsx and settings-dialog.tsx instead of `string`
- Localize theme dropdown labels (Dark/Minimal/Sketch/Simple) in
en/zh/ja/zh-Hant; keep proper-noun themes (Kennedy/Atlas) as-is
- Drop trailing colon from drawioStyleDescription and remove dead
switchTo/minimal/sketch keys in all 4 dictionaries
- Auto-sync drawio dark URL param when ui="dark" is selected
- Add aria-label to drawio-style SelectTrigger
* fix: use kennedy as default theme and label it "Default"

* feat: update about page examples with new diagrams
Replace old cloud architecture and cat examples with ResNet50, RAG,
Authentication, Agile Scrum, and Open Innovation diagrams.
Update all three language versions (EN, CN, JA) for consistency.
* fix: correct ResNet50 prompt text and keep prompts in English
Update the ResNet50 example prompt to match the actual diagram.
Keep all prompt texts in English across CN and JA about pages
since prompts are what users type into the AI.
* docs: update README examples to match about page
Replace GCP, AWS, Azure examples with ResNet50, RAG, Auth,
Agile Scrum, and Open Innovation. Keep Animated Transformer
and Cat Sketch. Keep prompts in English across all versions.
* docs: remove ResNet50 and Agile Scrum examples from READMEs

- Replace newyear-referral URL with new Coding Plan referral URL across all files
- Update model name from K2-thinking to glm-4.7
- Add volcengine invite poster to Chinese README and about page
Add full Traditional Chinese support for Hong Kong/Taiwan users by
creating a zh-Hant dictionary and registering the locale across the

Fixes diagram not restoring after refresh. The issue was:
1. DrawIoEmbed rendered with canPersist=false
2. Session restore loaded diagram into iframe
3. canPersist changed to true, causing iframe remount
4. New iframe loaded empty, losing the diagram
Now we wait for isIndexedDBUsable() to complete before rendering,
avoiding the remount entirely.
Address review comments: canPersist is set async after mount, so DrawIoEmbed
needs to remount when it resolves to apply correct configuration and URL params.
