A droplet which allows you to open Git-Gui from finder.

To install, http://code.google.com/p/git-osx-installer/downloads/list?q=label:Featured, and extract to /Applications/Scripts (you'll need to create the Scripts directory, likely). Then, find the icon, and drag it up to your toolbar. Keep it there for a few seconds until it "sticks".

To use, open finder to a folder with a git repository, and click the "Git" icon.

CHANGES

Version 2.0

• No longer require an open terminal to get ssh fetches to work. (uses an invisible daemonized screen session instead).
• 2 git-gui instances would be launched by the droplet. That has been addressed and should only happen on extremely rare occasions. (update - actually... it happens every time git gui takes longer than 0.25 seconds to launch, which is the case if git-gui and supporting libraries haven't been cached to disk. bummer)
• Now sports an AWESOME icon (thanks Jake Smith)
