First, let's imagine the most optimistic scenario. A complete multiple undo of everything in Mathematica, at 0 cost in performance and all developed by one of WRI's brilliant programmers outside work hours (just out of kindness or for fun) in order to make a free gift to all Mathematica users. Would I be against it? No way! I don't normally refuse free gifts (in case anyone was wondering) and I am sure I would find a good use for this sort of thing. Even if, instead fo the above, we were offered only a multiple undo of input text only, but also at no cost in performance or development time, I would not have any problems with it (even though I can't remember ever having found myself missing this feature). 2. On the other hand: even the most perfect multiple undo is unacceptable to me if it is going to make my computer unusable. I change my computer (I only work on Mac laptops) approximately every 3 years and I always find that near the end of this period it feels slower than my ancient Mac Plus (which I still have). I have no desire and can't really afford to reduce the length of this cycle. 3. As for the feature itself, I would of course like to have it under the conditions described in point 1, but other than that I can think of many other features I would rather have instead. I could, at this point, start listing them, but that would really be off topic and would require more time and space than I am willing to devote to this issue.
