Again not really a BUG but more of a unnecessary issue.
Currently the servers are pinged last when refreshing and filtering. This makes the refresh processes much longer and clunkier then it needs to be. By refreshing by ping > name/search > players > passwords in that order, filtering as you go. Players would be able to reliably join servers before the refresh is finished and without getting frustrated that they see all these semi full servers that are full by the time the refresh is finished.
While looking at the browser, you could also add new found items above and below the selected item.
This means that the selected item does not move its position on the screen. Just the new items and the scrollbar would change. Atm its annoying to select a server during the search and have it moved again before you can perform a double click on it or double click the wrong one due to “bait and switch” 
i would suggest chaning the browser in a few ways
when you selecte only objective, only ping and list objective servers rather then filtering out others after.
allow sort by number of players and ping.
highlight servers that have friends from your FL in them.
