some feature suggestions

[balanced]

This is super handy, thank you so much! And it's also very useful to be able to collapse the whole bus group with one button

Since track output selection is automatically routed to bus when dropping a track into it, I would like to suggest one thing: why not make it to change back to Master if you drag a track out of a bus group/folder? It would follow the same logic. If you drag and drop a track to somewhere, it's routing gets automatically adjusted.

Anyway, a big thanks!

Edit: I just discovered also that buses can be nested inside buses. Super cool
