I figured I'd finally use my blog for something, and once I was done writing it I fiddled with the image placement and didn't like it... so I tapped undo a few times (ctrl-z). I fooled around a bit more and went back again, and after a while I went back too far. Is there a 'redo' function, to go back a step before it undid my entire article, or am I simply a dumb asshole for not posting it then editing?
