I have just downloaded textmate and I looks like a very promising editor. I hope to be able to use it soon!
I would very much like to see an environment for both latex and python. Those two environments are those I am in most of the time. I am sure that I not alone.
Also, to me the tab behaviour of Emacs (where you can press tab anywhere on a line to align the content of the line) is a big plus when programming. It helps structure back the code rapidly. This feature would be part of a more global automatic formatting for programs but at least it is almost essential.
This being said, you are doing an excellent work!
Congratulations and I look forward to your next version which might include these features.
