I had this idea for some time but after seeing this mod I thought, why not post it.
Mod link Smart Crafter
My idea, maybe someone has alllllready posted something similiar but i was to dumb to find it ,
is that crafters reach level xy there will be an ability unlock that helps you craft stuff.
Like the Smart Crafter, after unlocking that ability the crafters does not need your help to craft stuff.
now you have to craft two iron ingot and then you can craft the iron mace
but with that level ability, the crafter will craft the two iron ingot automatically and then the iron mace.
