A Call Bubble Similar to When Someone is Streaming in a Server.

          When someone is streaming in a voice channel, a grey bubble with a monitor will appear in the top right of that server. However when there is someone in a voice channel, nothing will appear. I was thinking, what if you added the same thing, but with a phone instead when there's someone in a voice channel? It would make finding people to call much easier than hovering over the server (only for pc), or actually going into the server and checking to see if there's anyone in the voice channels. If someone starts streaming, then it would get overridden with the streaming bubble instead. I'm probably overexplaining this a lot, but hopefully you get the gist :p
