Bins for Timeline

While editing complex projects in the Premier there's no such thing as enough screen's "real estate" (especially vertical). One has to scroll and resize tracks to make them fit on the screen. Things get very bad at the end of the project when layers and layers of dialog tracks, foley sounds, and the score is added.
Suggestion: Allow grouping tracks into virtual Bins. The user should be able to create a bin that can have assigned custom name and group tracks in it. For example: Create a bin "Dialog" and put all dialog tracks into that bin. Then you are done working with it, "collapse" it to create a thin line representing all tracks combined on the timeline, freeing the space on the screen for other tracks. That way one can group and nest tracks in any order you want.
