Mods that have deep levels of crafting are fun, but can be a little frustrating. I usually end up making 3 stacks extra because I can't math. :) I'm looking for an item like a clipboard that will, when (shift) clicked on an item in JEI, copy all of the necessary components to create said item.
Example: Sugar Cane Exploder 9000 Mk2 Notch Edition
Redstone x 368
Miniature TNT x 6
Llama Heads x 11
Can be cleared in a crafting grid or shift clicked in the air. A snazzy interface with check boxes would be nice, but a plain piece of paper will suffice.
