An option to have the editor save all the things it normally saves when I exit it. Then, I set this option to execute every 10 minutes. As a result, I don't loose an hours worth of work (open files, look-ups, bookmarks, etc) when the editor unexpectedly crashes!
I see that I could almost do this with AutoSave, except that would require inactivity to fire the command. If I'm busy, I currently just have to keep reminding myself to exit SE every now and then.
