I've always felt that the project panel within after effects to be very limiting coming from a the perspective of a video editor As much as I've gotten very used to it, I cant help but feel it could be a lot better since it has barely changed since I first began using the software. I would love to see something more akin to Premiere's project panel in AE, but to me more specific, I'd love to see...
-Scale slider to change the size of the list in the panel and make icons bigger
-Double click to open up a bin in an isolated panel on it's own
-Freeform view for visual organization of assets
-Hovering cursor over certain assets provides a scrubable preview on the thumbnail.
