Pro Visual commit mode
Allows for interactive staging of files or hunks and deleting of unstaged or non-git tracked files. Hunk size slider allows staging/unstaging individual lines, letting you stage pieces of a file easily.
Pro Fast GUI
Responsive even with thousands of files or large binary like files
Pro Understandable trees (branches etc.)
The visualisation of the development trees makes git a lot more useful. The command line is good for a lot, but trees are for GUI clients like GitX.
Con Clumsy staging workflow
The staging workflow in GitX-dev is kind of clumsy and unintuitive in the opinion of some. (others love it)
