# File History and Restore

### Files with Unsaved Changes

Tabs show a dot (•) next to filenames with unsaved changes. The dot disappears after:

* Manual save (Cmd+S)
* Autosave (configurable interval)

### File History (Cmd+Y)

Nimbalyst automatically saves snapshots of your documents, providing version control built into the editor.

Snapshots saved periodically

* Manual snapshot on Cmd+S
* Compressed storage in database
* No external tools needed

* Cmd+Y opens history panel
* View > Document History
* List of all snapshots
* Timestamps for each version
* Preview snapshot content
* Restore history
* Current version becomes new snapshot. History preserved. Can undo restoration if needed.

#### Comparing snapshots

Just clicking on a snapshot will compare it to the previous checkpoint

Click on one snapshot and then command-click on the other to compare it to a different snapshot
