This is a tricky problem, and we have a couple of ideas. But currently if we're having a longer chat (double clicked will latch-open the mic) then we mute the other groups. Anyone else in the other groups will be able to see that you're muted.

We're contemplate auto-muting other groups when you have incoming audio. Would love to hear your thoughts as well.

When I played milsim games like Arma, a useful feature was to have my "squad channel" in my left ear, "command channel" in my right ear, and separate keys to PTT for each channel.

Did you find anything with those features already? I have a very similar scenario and I'm currently exploring what is available.
