Argos/BitBar plugin to manage git repositories quickly and easily through a simple menu system GUI.
Download either Argos for Gnome Shell or BitBar for Mac OS (I haven't seen anything similar for Windows, but please let me know if you do see something!). Then, install this shell script as a plugin. By default, gitbar searches your home directory for .git directories. Modifying this directory is as simple as modifying the find call near the bottom.
