Voice Chat new Feature idea!

So I have been thinking - many times I was talking with friends on discord and doing other stuff. They were talking, but it did not bother me for most of the time, but finally I needed to focus on something and I couldn't do it right, because I could hear them (I was still listening) - didn't want to mute myself or lower every single one of them.

So I came up with an idea, to lower sounds from chat you're connected to.
I think that would be a cool idea, because sometimes I really want to listen to everyone else, but also be able to do other things!
