Unfortunately for git-review, I don't think there
is a single GUI that
supports it.
There's actually no requirement for using git-review. It simply makes
things easier. If you set up the remote, and make sure to include the
commit-msg hook, you can use anything you want.
I haven't started using git-review at all. I'm still using the
aliases/remotes I originally made for the puppet repo.
