Very nice and seamless UI! I hope to use this sometime soon. Like other mention, closer repo access would be awesome (I suppose you'll have to authenticate with GitHub for that?). Support for BitBucket would be nice, as well.
Very nice! I would love to see something like this that compiles and gives the output in realtime, even if it is only done on the client. Would be very handy for tech-screens.
Thanks for the suggestions - agreed, it would be nice to see version history (and not too hard to add, the server already maintains the history for the operational transformation algorithm)
