Different Server/DM Suggestions

I’ve always seen the “time to ditch teamspeak and Skype” however there’s a few things I miss from TS that could be brought over, or in inspiration of. Channel tag icons - this shows valid permissions to enter the voice channel where necessary. Not really as useful on text channels. Password encrypted voice channels - this is the main thing I miss from TS3. I wish on discord we could password protect the channels, so that not even Sever Administrator can join without knowing the passcode. Read icon - a little like WhatsApp. How the blue ticks appear when someone in direct messages has read a message. I think it’d be highly beneficial. Regards, Reece
