- Admin features must be separate from the employee interface to avoid permission conflicts
- Calendar view should support monthly, weekly, and daily display modes, adapting to different screen sizes
- Statistics features should include visual charts (e.g., bar charts, line charts) for quick analysis
- Ensure the app remains stable under low-network conditions, with an offline caching mechanism
