There be dragons. The problem is that some things happen invisibly and far away from where you are, so you don't know about it and you don't find out for a couple of weeks. Undo and automatic backups are useless in that case. That *has* happened: there have been multiple postings in the ML about such problems. Whenever it has happened, the devs have always modified org to make it safer: that is the prudent thing to do and the correct course of action IMO. Hell hath no fury like an orgmode user who lost part of his/her precious org file because of an errant keystroke a month ago and was not aware of the loss until it was too late. -- Nick
