If I have useful stuff in a cell, but I need to edit it, and I'm afraid I might delete things I need, add things I don't need, change things that are already perfect... well... I just copy the cell and paste it above or below, and I edit the copy, leaving the original alone! Or, if there's a lot of editing going on, I copy/save the whole file! Later, when I've gotten moronic and made a mistake (it happens!), the original is still there. I can copy/paste between the two versions until I'm happy, the code's happy, and nobody else cares! That's WAY more flexible than multiple undo could ever be, isn't it?? I mean, what if the change three layers back was bad, but the last TWO changes were great (and time-consuming)? How can undo help with that? How can I even keep track of which changes were good and which were bad, with undo? I can't! WRI already provided copy, cut, paste, color-codes for missing brackets and undefined symbols, automatic structure-based indentation... haven't they done enough? Really, at some point, you gotta wonder... could it BE any sweeter than this?
