Would be very useful if we could paste a github file url and refactor.io could just render the file (or a portion of it based on the github url) rather than pasting code manually. Also, I was trying to comment on a code snippet I created. It would have been convenient to be able to refer to a specific line using shorthand (like #14, etc.) in a comment rather than pasting the entire snippet again with a diffed view. Still a cool and super simple idea.
