I dont know if i am first asking this.
When I play game, I can see some of my friends playing game.
But when the room set password and lot of players in, its hard to find host to ask password.
So I have to ask friend if he could ask host let me in(asking password)
I think this is kind of waste. And can be solved quite simple way.
So I think it would be great to show host when seeing joining player.
Just simple example
some kind of mark like star(which means this man is host)
