I didn't find (in my search) this specific feature, and it seems I may have suggested this back in X2, but...
Just as Tracks can be nested in Folders (Track View), I'd like to see a way where those same Track
strips could be collapsed into Folders (Console View). But also, to allow the Folder "strips" to appear as a blank strip with perhaps the labeling in vertical text. See the attached pic below. This is an ugly example, but essentially the first strip is the "folder", which can collapse the other strips quickly vs relying solely on archiving or using the Track Manager. The folder strip could also be thinner, not affected by Strip width settings.
Click on the bottom black box of the strip to collapse or expand. If collapsed, the "L" would change to a "+", for example.
Again, this could be made much prettier, but it would certainly make console strip management, including those used by ProChannel users to save some serious real estate.
