Saving, versions and recovery
Saved means persisted
Changes pass through the project’s revision-checked save queue. Wait for the saved state before closing a project with an outstanding edit. If saving fails, the error needs attention.
Undo and redo
Control/Command+Z undoes a saved change; Shift+Control/Command+Z redoes it. Related grouping and duplication work is saved as a single action.
Look back safely
Open Revision history to inspect an earlier version. Return to latest before editing. Restoring an earlier revision creates a new saved revision, keeping the previous state in history.
Conflicting changes
If another session changed the project, read the latest saved version and retry deliberately. Do not overwrite a newer revision with a stale assumption.
