Deferred Features (Post-Launch)

The following features are intentionally deferred and not critical for core functionality:

  1. Historical data sync - Can be ported from old plugin later

    • Location: old/main.lua:1059-1356
    • Complexity: High (requires statistics.sqlite3 parsing)
    • Priority: Low

  2. Network management on suspend - WiFi enable/wait logic

    • Location: old/main.lua:404-441
    • Complexity: Medium (device-specific APIs)
    • Priority: Medium

  3. Custom file logging - Write to dedicated log file

    • Location: old/main.lua:46-89
    • Complexity: Low
    • Priority: Low

  4. Force push/connect on suspend behaviors - UI exists but handlers not implemented

    • Complexity: Medium
    • Priority: Low

New Features Added (Not in Old Plugin)

  10. Auto-sync on resume - Background sync when device wakes up from suspend
  11. Auto-sync after session - Optionally sync immediately after session ends
  12. Book ID resolution during sync - Resolves NULL book_id for offline sessions
  13. Type-safe database operations - All cdata converted to proper Lua types
  14. Atomic upsert operations - INSERT OR REPLACE for better data consistency
  15. Retry tracking per session - Track failed sync attempts per session
