I'm a video producer and editor, and while I would never use this editor for creative editing, I think it does have potential. It feels a little like editing in old versions of iMovie, but is not as refined. It would be more useful if it had the ability to edit existing videos. Just as people constantly refine keywords and tags, the ability to re-edit clips in your existing videos would be helpful.
Maybe a choice in publishing methods? 'Re-Publish' OR 'Publish New'
The ability to import my own audio would be nice - narration or voice-over - would require an additional audio track.
