I would like the ability to mute (hide) specific users on the server.

I don't want to see what a certain person says in a chat channel,
In this case, I have no choice but to block that person,
In this case, I have no choice but to block the person, and I can't just "see what he/she says for a while".
I would like to be able to mute the chat and voice chat if I don't need to block the person, but it is bothersome to me.
