See who's on server feature?

Hello, I remember in the past I could see which server a friend is on (in the friend's tab). I can't seem to find that anymore, at least it's not in any obvious spot that I have thought of when trying to do that today.

There are 2 people connected to the server, but I'd like to know who they are. Is this a possible feature to be added on at some point? Even if you can only see people you're friends with (such as 5 people connected and you're friends with 3, you'd be able to see those 3 people in the server).

It'd be handy to see on the Server's list with the how many people are connected.

Thanks again!
