I've already filed a feature request on preserving undo history. I suggest adding a description of this more robust functionality to that request.

Hi, Just another feature suggestion. Use case:
I've been making some changes in a source file. I've been making the changes in two locations in the file in parallel, trying to keep them roughly in sync as I make the changes. When I get to the end, I notice that there was a simpler set of changes for one of the two locations.
I'd like to be able to select a region of text and 'undo in selection'. It is just like normal undo, but it skips over commands in the undo list that don't affect the selection and only undoes commands that do affect the selection. (For bonus points, the 'skipped' undo commands could be left in the undo queue, so if I start using normal undo then they start being undone.)
I suspect that this isn't a particularly common request, so I don't really expect it to ever be implemented, but I thought it was better to mention the idea than not.
Be well, Will :-}
IMHO, the current state of affairs with regard to undo really … stinks. (yay censorship!)
Not just TextMate, but most applications have really REALLY terrible undo systems. Some people are actually innovating in this space. The e editor http://www.e-texteditor.com/ for example has a really stinking sweet (looking, since I haven't actually used it) system. That editor actually manages all of the edits and lets you go back in time for the whole document or just a section and keep the entire backward AND foreward history preserved across edits and saves and closing and reopening the file.
I really really want this functionality in TextMate.
I really want to just close the document or quit the app and come back a week later and still have my full undo history.
Currently this is not doable with the current bundle system. I have investigated linking into the preview window since it can actually run a command every time you make an edit, but the limitations of this system are just too great to bother with it. It might be doable with a plugin, i have no clue.
I think we're just going to have to wait for Allan to open the door to this sort of thing, and I really doubt that it's going to be before TextMate 3.0. I'm sure the stuff in 2.0 will happily distract me from being too annoyed about it for now.
