Three things I'd absolutely love to see

1. Full custom skinning for the video player (custom full screen btn, volume slider, tracker, etc).

2. Audio player support (instead of having to work around by making a video without video) and full custom skinning for it.

3. The ability to embed video or audio, for example Vimeo

You guys are doing a great job so far, I love the program.

Flash is predominantly used for video yet none of the IDE/Tools really help skin/develop a video player.  Would be great to see extra skinning support for video players.
