It would be very nice to be able to drag a in and out time range of a clip.
To explain further.
You may have spent a while tweaking a time range of a clip so that it plays back and loops nicely with the tempo of a track.
You now want to play another portion of the source clip but over the same number of frames.
As far as I can tell presently this is only possible by readjusting the in and out points again.
This would be a very musical feature to have, and is implemented in a lot of other aplications.
Flowmotion is a fine example of a vj tool that has this feature.
Neuro mixer is another, even good old MyTime had this way back in 2000.
Having said that I must also add that Reso2 rocks
