Auto-save and revert to a previous backup

[Br4ssman]

I don't know how this will turn out, I'd rather propose it and it doesn't go ahead than leave it on the back burner.

Apart from "Apply" and "Cancel", what would you think if you could configure how often the programme will save by itself?

Besides, apart from being able to lose a project due to a power failure, map tree corruption or simply undoing the changes through the command system, sometimes it can be simpler to restore a backup.

Thank you.
