Taskmate ... the missing GTD tool for your editor: now out!
Taskmate is currently available as a TextMate bundle only. But as it's a pure Ruby implementation it will as well be capable to pimp up any other scriptable editor. As I'm currently using (almost) only TextMate I don't want to integrate Taskmate with other editors myself. But if you want to give it a try, I'll happily help you with that.
I highly appreciate suggestions, feedback, criticism ... and of course help and participation.
By the way the TextMate integration of this bundle is based on Henrik's bundle which was inspired by Taskpaper by Jesse Grosjean. Therefor the same licensing applies to it, i.e. you are free to modify and redistribute it non-commercially, though I would appreciate due credit.
Go ahead and try it out! It's cool :-)
