What problem would you like to solve? Please describe:
Improvements are sought for the Temporary Schedules feature based on recent user feedback.

Describe the solution you'd like:

1. History and Change Confidence

   • Add a diff feature to track changes in shifts. Changes include added or removed shifts, and added or removed users.

2. Timezones

   • Implement an app wide timezone setting defaulted to local. Always display time in local but provide an option to hover to view schedule or rotation-specific timezone.

3. Overlapping Schedules

   • Change the handling of overlapping temporary schedules to trim existing schedules instead of merging. Existing schedules that are overlapped by a new one will be truncated or split.

4. Shift Editing User Experience Improvements

   • Implement fixed shifts configuration for temporary schedules.
   • Make user selection a required field unless 'allow gaps' is checked.
   • Add a new feature to select fallback user or schedule to automatically fill gaps.

Additional context:
This updates are expected to enhance user efficiency and confidence when managing temporary schedules.
