TextMate 2 was released today as opensource. This is what I from a fork:
- Buffers, (split my window into slices and put tabs in each subwindow).
- Implement the interface in ObjC and everything else in a high level programming language.
- A package system with a online companion site.
- A online command line interface where I can call commands.
Essencially what I want is emacs but well done and integrated with Mac OS X
