Greetings A/all,
I'm surprised this suggestion hasn't already been made - or if it has its not recent and I've searched for "participants" without result.
Lots of times people enter they chat lobby and immediately leave. I'm sure a significant number of those times is when that person wants to know who is in the chat room, perhaps looking for someone [s]he knows or suspects may be in the lobby. It also occurred to me that if that other person has gone into a side room at that moment they won't be found by the searcher.
So may I please add to that long long wish list a suggestion for an extra tab (button) providing a list of participants in each of the chat rooms.
All the best
VV
