## Summary by CodeRabbit

- **Bug Fixes**
	- Improved presentation mode to preserve your current panned view when exiting pan mode or toggling fullscreen, preventing unwanted viewport resets.
	- Spacebar actions are now correctly disabled when using the frame navigator tool, avoiding accidental tool switches.
- **New Features**
	- Enhanced presentation controls for smoother transitions and better handling of user navigation states.
	- Added a one-time toast notification for presentations without frames, shown only once per session for better user guidance.
