Sorry; I had looked in the archives, and saw first mention of this
back in February, so assumed that it had been implemented by now. I
hate to belabor this, but from what I've read in the archive, a lot
of people are asking for "normal" undo, so I hope its high up on the
todo list (if there is an ETA, that would be helpful to share).

HUMAN? How dare you! :)
I don't know from ATSUI, but I assume there is a good reason you're
using it rather than TextEdit or NSTExtView, given what you indicate
are optimization compromises.
As a new user to TextMate (and having been in involved in number of
development projects), I can't help but bring the baggage of being
used to certain performance, behaviors and expectations from a Mac
application, so please forgive if I come off a bit frustrated. It's
tough competing in this space, what with the 800 lb. BBedit, and its
a testament to the work done thus far that I'm using TextMate a bit
more now, if only for the integrated project drawer and code-
btw-- how about making the Language label in the window a drop-down
menu to change language on the fly? :)
