Sounds really cool and at time, as I learning and diving into Emacs...
Is it org-mode compatible? As minor mode it should?
Looking forward for the Release, thanks for making it.
If you want to try it out for Emacs, you can get it from github. If you do, I'd love to know if it works for you. Also, are you active on your dice.camp account? I tried contacting you there earlier.
