You’re right, it’s not a huge problem. But in comparison to Pro Tools’ Bus-system, it’s a bit more cluttered in the “Visibility”-list. It’s unnecessary to have a huge list of busses in the “Visibility”-list, when I only use those Buses as routings for other channels. In Pro Tools, the Buses aren’t “real” channels, but only functions as routing-devices. If I would want a Bus to be an input- or output-channel, then I would just have added a new input/output channel. I don’t see why Steinberg has forced the Buses to be input- or output-channels, instead of just letting the Buses be means of routing.
