History

Open History in the rail to see every version of the document. Every save is a version, made on its own at natural pauses while you edit, and on demand with Checkpoint now or ⌘⌥S.

The now card at the top reads Edits since the last checkpoint while you have unsaved edits, with Checkpoint now beside it. Rows group under Today, Yesterday and the date; a long day folds behind Show N more checkpoints.

Press a row to compare: the version docks read-only beside the live canvas, up to three at once. Escape closes the compare. The row's menu holds the rest.

• Restore vN brings that version back as a new version. Nothing is deleted.
• Discard edits since vN, on the head row while you have edits, takes them off and makes no version. The confirm reads: everything you changed since it comes off; the checkpoint comes back as it was saved; the history is untouched.
• Revert push brings back the version from before a push, as a new version. The pushed version stays in the history.
• Name… gives the version a name, such as calmer intro, and a note to whoever picks it up next.

When a new version lands while you edit, the now card reads Checkpoint paused and offers Review; drafts keep saving while you decide. See Save and autosave.
