I'm always keen to try out new plugins, so thankyou. It's not quite clear from your description exactly how this behaves but I guess it's best to try it and see for myself.
Thanks! I kept the description to the list as brief as possible, but on the other hand the README in the public Git repository on GitHub tries to be very complete.
So, just surf to http://github.com/unwind/gitbrowser/ and read the documentation there. It even has screenshots! :D
Looking forward to any feedback, on- or off-list as you please.
