I have a single large stack of a material. It's quite difficult to go "gather" four times if I need four of one object. Isn't there some way for me to break up a stack in an equal amount of pieces?
To split a stack in half, right click it. To put an even amount of something in a crafting table or chest or your inventory, hold left click on the stack and drag the stack in the shape you want it to be. If you drag the stack over a slot you already placed an item in, it will not affect the slot of items.
