Channel divider in mixer

Sometimes with big sessions it can get a bit messy in the mixer.I know there are ways to toggle visibility etc but how about a divider?What i mean is lets say you have all your drum tracks and then a drum buss,then all bass es then guitars etc.What if there was say a blank panel you could insert after the drum buss,which would separate the drums from the bass tracks.Then one after the basses to separate them from the guitars etc.Nothing thats gonna take up real estate but just enough so things seem tidier.Could have the option to hide dividers or name them etc and maybe jump to next divider,insert pics on them too.
