I'd like to see a controller have a drop-down on its bottom edge. When expanded, it would list all items slaved to that controller. Sometimes it's easy to forget how many different things are linked to a given controller. It should be organized by instrument or effect followed by a colon and then the dial or setting being controlled. Might also be nice to have an option to disconnect controlled items while viewing this list.

I know all there is now is the Peak, LFO, and MIDI pass-throughs, but if additional controller types get added - being able to keep track of such details would become even more important. (Some might even argue for a patch-cord type view, but sometimes even that gets too cluttered too. A list or tree would do for now.)
