I'd love to be able to use the output channels (like output 1-2) but also use them internally (as special busses). So being able to have extra output channels just to use as busses. This would really help keeping bigger projects easier to navigate through...
Now often there's busses for fx (if I want to send it to other stuff afterwards) and busses for instrument groups. Some busses I prefer having next to the output, some I prefer having next to the instruments they apply to.. I know I can drag them around, but it often becomes quite a mess in bigger projects. being able to have all "output" busses next to each other would be really handy..
