It would be the only feature that is missing for me to switch over to sublime 2 which I am absolutely in love with. It is soooo fast, stays out of the way and works the way I expect it to. There is a genshi package for sublime that could be used as a basis, located here: bitbucket.org/sublimator/genshi/overview
I am not sure if this would be compatible with sublime 2. The docs are still being written but a quick glance seems to look ok to use as a base.
So good job on Sublime 2 and +1 for "Django Template" support!
