+1 on this request. I’m actually installing an SQ today, but will have this same issue on a QU shortly.
Church setup. Want to be able to mute the whole band during the sermon. But that’s most of the channels, and no one wants to see all that flashing throughout the whole sermon.
The GLD had a separate LED beside each mute button to show this. Without that, I’d suggest the LEDs be half-lit (half brightness) when muted via group. Or I’d be fine with all of the channel mutes being solid and the Soft key flashing instead.
