Indicate Chaels Muted in Aux and Effects Mixes

The Input screen on the big display for a chael helpfully includes small bar graphs giving a rough idea of which Aux and Effects mixes a chael is in. But, if you mute that chael in the Aux or Effects mix, those little bar graphs don't change. I think it would be helpful if those bar graphs changed color (perhaps became black or red) to indicate that, while that chael is in the Aux or Effects mix in question, it is, in fact, muted in that mix.
