First Drupal.org GIT Commit
The company I work for uses this module quite a bit (well, mostly the IT department) for our systems management tracker. Having a nice clickable, toggle-able todo list is nice for those long maintenance nights.
Anyway, it's used constantly and I have improved it quite a bit and I ported it to Drupal 7. The previous owner of the project has not implemented patches, fixes, or improvements for about 3 years now, so my boss gained ownership of the project and I committed all the fixes.
So this is a nice step for me in the Drupal world. I am now an official contributor!
