TODO - Future Improvements

High Priority

Unsaved Note Switching

Current Behavior: When a note has unsaved changes, switching to another note is completely blocked. User must either save or discard changes first.

Proposed Improvement: Implement local session storage for unsaved changes:

Store unsaved note content in browser's sessionStorage/localStorage
Allow switching between notes without losing unsaved changes
Each note maintains its own unsaved state independently
Unsaved changes persist across note switches but don't trigger server sync
Visual indicator shows which notes have unsaved local changes
Only sync with server when user explicitly saves

Benefits:

More flexible editing workflow
Can work on multiple notes simultaneously
No data loss when switching notes
Better matches user expectations from modern editors

Technical Approach:

Use Map/Object to store unsaved changes per note ID
Key: note ID, Value: { title, content, timestamp }
Load from local storage on note switch
Clear local storage on explicit save or discard
Add visual indicator (dot/asterisk) on notes with local changes

PDF Export Styling

Current Issue: With custom Google Fonts in place, PDF export produces broken layout and styling. The jsPDF html() method doesn't properly handle web fonts and complex CSS.

Needs Investigation:

jsPDF may not support external web fonts properly
May need to embed fonts or use fallback system fonts for PDF
Consider alternative approaches: html2canvas, puppeteer, or server-side PDF generation
Ensure proper markdown rendering with headings, lists, code blocks, etc.
Maintain consistent styling between preview and PDF output
Consider bundling Google Fonts locally for offline support and better PDF rendering

Offline Mode

Current Issue: App fails when internet connection is unavailable. No local caching, no change queuing, no sync on reconnect.

Required Features:

Local-first storage of all notes (IndexedDB or localStorage)
Work offline seamlessly - create, edit, delete notes
Queue changes when offline for later sync
Detect connection restore and push queued changes
Conflict resolution when note changed both locally and on server
Visual indicator showing online/offline status
Show which notes have pending sync

Technical Approach:

Cache all notes locally on successful fetch
Intercept all API calls - if offline, work with local cache
Maintain a sync queue: { noteId, action, timestamp, data }
Use navigator.onLine and 'online'/'offline' events for detection
On reconnect: process queue in order, handle conflicts
Conflict strategy: last-write-wins or prompt user

Synergy with Other Features:

Pairs well with "Unsaved Note Switching" (both need local storage)
Bundled fonts ensure app works fully offline

Medium Priority

Other Improvements

Add keyboard shortcuts (Cmd+S for save, Cmd+N for new note, etc.)
Implement note search within content (not just titles)
Add tags/labels system as alternative to categories
Export multiple notes at once
Import notes from other formats (Markdown files, etc.)

Low Priority

Nice to Have

Note templates
Rich text paste handling
~~Image upload/embedding support~~ ✅ (viewing attachments works, upload TBD)
Note linking (wiki-style)
Version history/undo for saved notes
Customizable editor themes
Font size adjustment
