In the key editor, when editing tracks, every time I switch to another track or a combination of tracks, the controller lane is visible, which I don’t need during the editing process. I can of course turn it off (and I have a shortcut to do it), but it’s an annoying waste of space (particularly for laptop uses with relatively small screens) and, in my opinion, not at all necessary during most of the work. I think it would be quite useful to have a preference setting that avoids automatically showing controller lanes.
