No one is happy when their work is lost, so we regularly back up your work.
It also is useful when you can look at earlier versions of a scene to see how your work has evolved over time and even bring back bits and pieces that you might have deleted.
This also means you can undo and/or redo any mistakes.
Versioning
The system keeps a history of all your changes for the following items:
Snippet content
Codex: description
Codex: notes
Scene summary
Scene content
Custom prompt instructions
Opening the Revision History allows you to restore any version at any time.
You can typically find the Revision History near the field or a context menu next to it.
Restoring a Version
Clicking on one of the history buttons, a modal with the version history will open up.
Here you can see all the versions that are available for the item you are looking at. Once you select your desired version, the contents pane will show you the state of the item at that point in time. The restore version button will replace the current version with the selected version.
