As a user I want, that the mute-key is flashing/blinking whenever there is a channel muted, but the mute-mode is not selected, so that I can quickly recognize, that there are muted channels, even if another multimode is selected.
Rationale:
As of now, when I mute a channel and then switch to e.g. the solo mode (in the multimode section), then there is no visual way to recognize, that a channel is muted. The mute-mode switch is off.
So when I forget that a channel is still muted and the meters are in PFL mode, there is no hint, that the problem is the muted channel.
The same applies for the solo-mode and for the "usb/firewire"-return-mode.
