What about a friends list. Say your on a server, and there's someone who's friendly, or you like. So you go to the player list, you double click on their name and it asks, ''Do you want to be friends with this person''When on server list, you click the ''Friends List'' (a button down the bottom of the server list window) and it show all of your friends that are online, and what servers that are online.
And what does this have to do with the topic?
Something to tell if your server is up or not. There are to many idiots hosting servers that are not port forwarded. They should also make something that you toggle to auto weed out non port forwarded servers from the list every time you refresh.
