Actually, the reason greyed out notes are pretty much a waste of time goes far beyond how sloppy and chaotic things get when you consider the number and selection of tracks to be "ghosted". The point is, greyed out notes wouldn't be edited. Once you get into the question of "how do I go ahead and actually enable 1 or more of those ghost tracks so I can make changes, that's when you realize how limited and inefficient this approach is. That's why it would be better to just provide a quicker way to access another track. All that's needed would be a simple pull-down menu displaying track names (sorted by track number).
