Every save is recorded with who made it and when. Restoring one writes a new version whose contents match it, so the history is never rewritten and a restore can itself be undone.

Every save is recorded with who made it and when. Restoring one writes a new version whose contents match it, so the history is never rewritten and a restore can itself be undone. The newest version is what is running, so restoring it would change nothing and it offers no button.
