Improved Syntax Highlighting
It would be great if syntax highlighting could already be seen in the edit mode, or at least in the preview mode, otherwise it is a real surprise when all of the sudden some code is highlighted you did not expect.
It certainly surprised me the first time.

As a note: When I am trying to manually set the code class to "no-highlight", sometimes it works and sometimes it completely messes up my slides.
