It is a very frustrating experience to filter servers because the cursor keeps changing focus to the list of servers, so I will end up accidentally connecting to the wrong server. Then I have to wait 15 seconds to exit, wait for the server browser to cooperate so I can get into the server I need to be in, and then wait 90 seconds to log in.
This is especially aggravating after a server performs a scheduled restart and I end up getting stuck in the overflow queue because I couldn't log back in fast enough.
