Hi. Here is something I've done just in photoshop (I didn't coded anything) which means that this is just an idea of what the client might look like ;)
First of all, here is blank design without any filled info:
Now here is the design filled with info,
and you can see cursor at one of the server hostnames, that means if you click on servers hostname, number of players or ping you get more information about that server on the left side,
with button CONNECT which connects you to the server.
Also, I forgot to add the "Add Server to fav." button but it can be easily added maybe to the right of nickname bar or to the left of favorites button (heart).
I receive every praise and remark on my work and I would be grateful if you would leave your opinion as well :)
