I would like to see a bin where you can drop clips, both from clip monitor and timeline.
I often find myself having clips that I want to use but not right now. Finding great sequences when looking for something else but not having any use for it right now or lifting a clip from the timeline because it doesn't fit as good anymore but you want to keep it for later use.
I've solved this by having a muted track in the timeline where I drop these clips. It's not an elegant solution and the timeline gets cluttered.
Having a clip bin would be a huge help in organizing projects.
(By clip I mean a smaller piece of a larger clip (as in the project tree) defined by in/out points.)
