Enable Fullscreen
plugins:

Automatic Zoom State Persistence
The plugin automatically saves the zoom level and pan position for each diagram to your browser's localStorage. This means:
- Persistent Settings: Your preferred zoom level and position for each diagram are remembered across page reloads
- Per-Diagram Memory: Each diagram on a page maintains its own zoom state independently
- Automatic Cleanup: Saved states older than 30 days are automatically cleared
- Reset Functionality: Using the reset button clears the saved state for that diagram and returns to the configured initial zoom level
This feature works automatically - no additional configuration is required. The zoom states are stored locally in your browser and are not shared between different browsers or devices.
