This is neat editor and it's cool to see how Github could eventually bill itself as your one stop shop for code editing and collaboration. My only concern is that of feature creep hurting the user experience by creating a cluttered and confusing UI. I personally feel that Github's web UI is very cluttered as it is. They possibly have one of the best user experiences that I have seen, given the large amount of data and information that they have to present and I do not think that this feature necessarily hurts it at all, but it's getting close, in my opinion. Just my two cents.
