Pings

Hello I would like to suggest something. I happen to be in some servers that keep pinging everyone or spam pinging, however when I first joined them I placed them in a map and didn't turn off the notifications but I'm in like 60 of them idk. So here comes my suggestion: It would be awesome if you could mute an entire folder, I don't think that I am the only one with this problem. And if i mute them all sometimes I do want the notifications of all the servers and then I could just Unmute all.
Thank You FireFlower
