Hey i noticed there are a load of upgrade things that come with steve's carts and i have only just now found out they attack to the sides of the cart assembler itself with shift + Click and they each seem to do differnt things but i cant work out how they all work, can someone update the wiki to actually notice that these exist? someone who knows something about them would help
