I think that there could be a special items that is a map. When you open it, you are faced with a double chest with several books in it all having the server numbers in it. When you shift click a book, you teleport there but the map does not stay with you. This can be useful for new players who do not know the command but they do know this special item can switch servers for them. What do ya think?
jk! I remember suggesting this before they implemented /tutorial. I like the idea but personally I think they should make the command /tutorial pop up with a GUI with the server numbers in book form.
I was hoping Chest Signs would work similarly to this when they came out, but if a command is used it is only displayed in Local Chat.
Why not make the GUI appear with the "/server" command excluding the server you are on? Changing to the server you are on crashes your game.
