When I am in any Mix-Bus (Main, Aux, Group, etc -> blue Mix-button of the Mix-Bus lights up) and I hit the Assign-Button in the middle of the console, I would like to see all the mix-LED light-up of those channels, which are assigned to the chosen Mix-Bus.
I know well, that at the bottom of the channel-strips the information about the assignment is grey when not assigned and coloured if assigned. But the additional LED in the mix-buttons of the individual channels would be easier to see.
