I am a longtime Textmate user on the Mac who likes to keep some ties with the Windows world... I have been looking for a decent counterpart to Textmate on Windows, but quite frankly the best there is right now is Emacs, which is, well, Emacs
I was shocked to find out about Sublime Text, almost by accident (from an off-hand remark in an e-texteditor forum, no less). Anyway, it's simply BEAUTIFUL: I love the themes, the syntax highlighting, the snippets, AND the Python extendability of course.
BOTTOM LINE: what is the status of LaTeX support? I have tried out the snippets; some are OK, many need fixing (easy: e.g. the "\" is missing for some snippets, because it is not escaped correctly in the corresponding xml file).
I think I can start working on a more complete set of plugins/snippets/commands to provide a good LaTeX environment. There are many easy things that can be done---e.g. provide a build command (using texify), a command to launch a previewer (I like SumatraPDF, which gives you inverse and forward search with PDF files), fix the existing snippets and maybe add a few more simple commands. These I could do relatively easily. More long-term stuff (but essential IMHO to provide a competitive alternative to the wonderful Textmate Latex bundle) would include e.g. insertion of citations and references.
I'd like to try to work on some of these things in my spare time. However, if somebody else has already started working on a Latex package, I'd be just as happy to help out.
