I've been looking for an add-on like this.
You know how if you go on Blockland and join a server for a while, then come back and the server list doesn't change? I want a refresh button for it so I can see up-to-date servers. Also, sometimes whenever I try to join a server and it begins to repeat "Sending challenge request.." (or something like that) and it only fixes itself if you refresh the server list by exiting blockland and re-opening it.
So yeah, is it possible to make one of these?
