I use H, Track Manager, to select and show/hide tracks all the time. That's a great control.
Even if I've hidden tracks I'm not using presently, I still can get too many tracks to conveniently look at in the Console View.
It would be neat if I could open up a folder in Console View to look at my guitar tracks, and then collapse the folder like in Track View.
Then in Console View I could open say a folder of keyboard tracks and look at those for mixing.
I'd just like to have less left to right scrolling in the Console View (I already use narrow strips).
I also like to see the buses, so screen real estate gets taken up.
That's why expand / collapse Track Folders as an option in Console View would be useful to me.
