Looks good, the landing page could be a bit clearer - some more screenshots would be good. At the moment all the images just look like GitHub screenshots.
Is there anything from the content that you dont understand, that I could make clearer?
Is this something that you would use?
The side-by-side diff feature is buried at the bottom, and the whole page seems to imply that there are other features within somewhere, but I can't figure out what they would be (I would love to see screenshots of them!).
I'll also work on some better screen shots!
Thanks once again for taking the time!
