First impressions is that the minimalism compromises usability. I did have to think for a moment. (1) The control panel hides really long lines. (2) Really long lines! A bigger gutter would be good on the right hand side. In fact, that would free up the entire right hand side for the controls and whatever else. (3) The colour scheme got in the way for me, especially with syntax highlighting. Increasing font size drastically improved it for me so I have to ask, have you considered a bigger default font. (4) Would be cool if you showed a list of recently edited documents (via cookies or whatever). That way I wouldn't accidentally lose stuff.
