Why can't we have an undo button again?

Here's a purported proof of free will, in case anyone might find it helpful for future discussions about accidents vs. mistakes: http://home.sprynet.com/~owl1/fwill.htm

In my opinion, there's not a whole lot to be gained from a debate about whether "try harder not to make mistakes" is a satisfactory answer to "why can't we have an Undo button?" It seems to me that the best thing is for everyone simply to voice their opinion about how much they would like to have a FoW-Limited Undo button and hope that Alex and Adam see the thread and consider it important enough to warrant spending man-hours on implementing it.
