Allan,
First, thank you for creating such a wonderful editor. I've been using it full time for almost a year now and love it very much.
I've been trying to be mouse less when doing development with TextMate and iTerms. One thing I feel a little inconvenient is when I have opened too many tabs, I can not drag files from vertical list to tabs. Also, there is no keyboard shortcuts to move current tab to re-order tabs. Please add them to your feature requests if you feel they are interesting.
Regards,
Cao
