Mix Console Channel Visibiliry

I find the mix console configuration options in Cubase absolutely invaluable. Being able easily to switch between, say, all audio channels and all FX and bus channels at the press of a button is great.

I wonder though, if it’s by accident or design that if I want to hide an individual channel, I can only do it if that channel is set to the middle zone. If select a channel in the left or right zones and hit Hide Selected, the channel stays visible.

that’s by design

Ok, thanks. Can anyone expand on the thinking behind this design?
