You can clone with
HTTPS or Subversion.
how do you install this?
Seriously? How the heck do you install the Safari Extension. It hasn't been compiled as an extension. It's just a folder filled with a bunch of resource files. Not enough coffee today?
i figured it out and built the extension. you need a developer certificate and stuff. their current build works, but not super gracefully. I'll use it for a while.
With the CRX file you can just download it and run it from chrome, it will ask you to install. It's a lot easier than building and getting a dev certificate for chrome.
Have now added links to compiled versions in readme.
