When adding an audio track, midi track or similar, the track is added where you are at that point in the arranger window. BUT if you ad a group track, its added to a folder somewhere and you have scroll around to find it (losing the flow of where you were). With busses, this is a hughe problem. Say:
you have a project with 5 busses called Bus 1, 2 etc. And you ad a new buss… which one did you actually ad? Would be way better if it ended up just where you clicked.
