Git is great. The git command-line tools allow you do do all sorts of SCM gymanstics, but are hard to use if you're a designer just trying to commit the latest CSS file and push it out to your integration server.
It would be really awesome if it were possible to have the app call out to shell scripts to perform certain gestures. Many development teams have custom scripts for their workflow, and it would be great if this GUI could easily let folks use that workflow without touching the command-line.
