==Additions==
=== Blocks=== 
; Crafter
*A block used in automatic crafting.
**Items can be stored, put in and out on a crafter either manually or using hopper.
**If the item arrangement on a crafter matches the recipe of an item, that item will appear on the output slot, just like what a crafting table does.
**However, unlike the crafting table, item in the output slot of the crafter cannot be pulled out by mouse. Instead, the crafter ejects the items on the output slot when powered by Redstone, and wastes the material(s) that made that item.
**Right-click on an empty slot (that's not an output slot) on a crafter to "block" it. A "blocked" slot don't allow items from hand or from hopper to occupy the slot. Right-click a "blocked" slot to turn it into an empty slot.

*Use to connect with redstone circuit.
