Played with it a bit, and it has promise. I immediately ran into a few issues:

1. No way to edit just a file, you have to create a project. 2. No way to exit full screen mode.

Will be good for Django developers, for sure, but for us non-Django folks, it does make some poor assumptions in its code inspector, specifically with regard with templates. It kicked out plenty of errors in my perfectly valid Tornado templates.
