Looks like a great update (line-by-line committing ftw). I mainly use GitX for git GUI duties, but this looks like it's ready to replace GitX.
It's very handy to be able to switch between projects easily from within the app, and the direct GitHub integration is icing on the cake. The only not-awesome thing I noticed is some general lag and flickering, but hopefully that'll get worked out soon. The team at GitHub is doing some fantastic work.
This is definitely a great update and it's getting close, but for me this still can't replace gitx. I absolutely need something that can show a tree-view version of the repo branches. Even the CLI can do this. The web UI has the network graph view which is ok but not great since it doesn't really show branching.
It's so tempting to use a list-view because it looks nice and simple, is easy to implement and it hides complexity. The problem is that I need a view into that complexity to use git. The git model is a tree (or graph even) and to not display it that way just makes things harder.
