I did incorrectly make the generalization that "nobody is suggesting". My apologies for that mistake. I should have narrowed that to say that "those that want a reasonable implementation of multi-level undo is suggesting". My inference from the OP is that a typical multi-level undo in the "MS Windows or Apple application multi-level undo" paradigm was the desire. It's as simple as that. Others decided to make it much, much more complicated. I've followed the entire thread. A thread that turned into a mish-mash of well meaning, but "off the initial point", posts. Some posts are talking about autosave, which is not the undo that the OP refers to, in my opinion. Or, some have implied/suggested that the feature might need to undo kernel states. That just turns multi-level undo into a massive, unnecessary feature, again, in my opinion. You asked for a quote... one of your posts is one of those that would seem to argue against multi-level undo because it might slow down your computer or the WRI developers from more important tasks. If you're not arguing against, then I don't understand why you posted to this thread and why you made the following statements. ---Andjez Koslowski wrote:--- There are a few features that are useful to everyone, and there are many that are useful only to some but (unless they are made somehow optional), will slow down everyone, forcing people either to get new hardware or give up other features that they really need by having to stick with older versions. I agree that a multiple undo would occasionally be useful, but I certainly would not pay the price of having my computer paralyzed for a few minutes every time time I save. Besides, I can think of many other features, more directly relevant to the main purpose of Mathematica, that I would rather have than this one. Of course a simple kind of multiple undo, one that only undoes typing and not evaluation, might not present any problems, though it would hardly be worth making so much fuss about. Anything that would bring my computer to a halt is unacceptable to me, however nice it might be for people who alsways have the latest hardware. All I wanted to point out is that there is also this aspect to features like this one and I hope that WRI does not forget about it when designing new versions. Andrzej Kozlowski --- I will not reply to any future dissections of my posts by you.
