In Creative Mode, of the items for Storage, the Cupboard is missing.
Oddly, when in Creative Mode and you spawn Cupboards into your inventory, when placing them on your bar, you can place them without using any. Infinite placement despite having a limited number. Feature or bug for Creative mode?
EDIT: Found Cupboard under Furniture. Yeah, I suppose its technically furniture, but given that its a storage device, I really think it should be found under Storage. Maybe list it twice?
