As I'm working here I'm noticing I like to flip up the bus pane frequently. Now I wish that Shift-B was the browser and B was the bus pane...but I think if they were switched now I'd go insane.
 
Anyhow, what I notice is that I have two preferences for the bus pane height. Sometimes just rubber banded to a specific bus and sometimes for several busses. So, how about a modifier key or an options for more than one default height? I suppose I could use a screenset but it would be nice to have it's own functionality so I could bind it to a different key. Maybe a dedicated key cluster for variations?
 

I do the same thing when working. Everyone once in a while I will have the bus completely minimized, but 45% of the time I have it so I can see more tracks, but still see the bus area and the other 45% of the time I have it so I can see more of the bus area, but still see the tracks. The ability to have a couple sticky spots that you could key command would be awesome.
