Suggestion: Force User-specific mute.

I didn't know what to call it, but basically moderators on Discord servers should be able to mute certain people for certain people.  To make it clearer, if you don't want someone to hear someone, but you don't want to server deafen someone, you should be able to mute that person for them.  eg.  if you are in a staff call or a meeting and you don't want a certain person to hear one person, but they should be able to hear the other, you can mute the people for them that they shouldn't be able to hear, and do nothing to the people who they need to be able to hear.  It makes it easier for people if you don't want someone to move to a different voice channel, but someone shouldn't be heard by a certain person.  I hope this makes sense.
