One of the main draws of TextMate for me is that it is a light weight native Mac OS X application that can be used to edit everything quickly, has excellent syntax / plugin support to make it a joy to do any type of editing in that really no other text editor I have used seems to be able to replicate as well (lots of plugins for Vim and Emacs, but none seem to provide the same polished and quick feel).

What I fear is that if 2.0 ever did reach a releasable state it will no longer be a light weight application I would use to edit everything from plain text configuration files, code, or a simple todo list. It won't have that same light weight do everything feel to it that the current version has. It will feel like a Visual Studio or Emacs. Which are good for their main purposes, but would you use them to edit a fairly small and simple configuration file?

TextMate, in my opinion is still by far and away the best modern day text editor available on any platform. I do like vim, but being a native Mac OS X application, TextMate wins out the majority of time (just drag a file onto the dock icon or typing mate . when in the terminal). It's visually pleasing and fast to open, browse, navigate and move around in.

The only features I really would like to see added is split panes/windows and full screen mode. Nothing is more awesome than MacVim with full screen mode and 4-8 split panes (on a single 2560x1440 monitor).
