The original GitX is not actively maintained and needs a replacement.

The original GitX (L) hasn't received any update in the past two years, while [GitX-dev](http://rowanj.github.io/gitx/) is active and has gained some really nice updates to the overall functionality.

> GitX-dev is a fork (variant) of GitX, a long-defunct GUI for the git version-control system. It has been maintained and enhanced with productivity and friendliness oriented changes, with effort focused on making a first-class, maintainable tool for today's active developers.
