I'm amazed that anyone would argue against a multi-level undo for notebook input text corrections. Especially, that it would take processor time away from the CPU or development time away from the developers. I don't think anyone is suggesting multi-level undo for input and output. I use some drawing/image processing apps that do muli-level undo on very complicated images with "no problemo". Seems like this would be a piece of cake challenge for the wizards at Wolfram.
