Right now the only way to view an asset without adding it to a composition is my watching it in the Footage window, which is a bit slow and clunky to work with.
It would be really useful to be able to scrub through assets like videos and sounds faster to recognize them.

One way of approaching this would be to match the Project Window/Media Browser with Premiere Pro's a bit more.

An other would be to improve the footage window by making it more responsive so it could be used as an video previewing tool.
