If you, like me, hate deleting branches by doing `git push origin :branchname` and `git branch -D branchname to delete a branch. Try out git extras by visionmedia. Its a set of great extras for git that makes some of the more trivial tasks way easier.
You can download the source here `http://github.com/visionmedia/git-extras`
– or use brew to install it via `brew install git-extras`
