ALT+Q to toggle the queuing mode between back queueing(default) and front queueing.
This version adds a map setting that allows the admins block new recipes if the recipe queue limit has been reached.
There is also a command /crafting_queue_list that can be used to list the mode and count of all the connected players to help track who might be causing the server to lag.
