Just a suggestion here. I read a post today by Andrew Ozz explaining how to easily restyle the visual editor in the WordPress admin panel. I was wondering if this might perhaps be a good thing to include in Hybrid.

Perhaps a CSS file could be checked for in the theme folder and when present, loaded to restyle the visual editor to act as a real wysiwyg editor.
