When there's a bigger ensemble and gazillion of midi tracks (possibly forming instrument groups), it would be great if there was a possibility to make folders for the tracks. I would personally prefer Cubase-like implementation, so the tracks within the folder just get tabbed a bit, but they're still in the same view. So definitely NO folder tracks like in Logic and no separate windows for the folder contents!!! The folder would just bundle the tracks and you could hide it's contents if you wish, so you'd get a clearer view.
Each folder should have routable output and possibility to put effects too.
Track folders
Well, as long as there was a way to hide tracks. Routings are cool too, but they can be accomplished with the current tools too... hiding tracks out of the way my main wish too.
