Experiment with a GTK popover to hold the trimming preview right over the trimming handle
Submitted by Jeff F.T.
The "live trim preview" feature (http://jeff.ecchi.ca/blog/2012/03/07/trim-like-a-professional-hair-stylist/) could be made to work in a GTK popover holding the trimming preview right over the trimming handle. I think it would an improvement as the eye would stay contextualized (given a reasonably sized popover ;), it would look nice visually, and allow keeping the view of the frame at the playhead in the viewer at all times.
