It is odd/weird to have two crafting tables - the one you walk up to and at which your animated avatar works and a second one hovering somewhere in the air, on which you place crafting items. Is there a reason crafting can't be designed in the same manner as houses, i.e., where you could place your crafting items on the table in front of you - as you can place items on a table in a house - instead of on the floating table? Also, is there a reason why you can't leave a produced item sitting on the table while you produce another? For example, suppose you smelt ore and make an ingot. As a result the ingot and smelting hammer are sitting there. Then you add another iron ore and another chunk of coal, hit CRAFT and the table would have two ingots and the smithing hammer, etc. It's one thing to require the exact number of tools and raw materials required for making something; quite another to not allow anything else on the table. Indeed, why not allow all relevant tools to be placed on the table (normal work practice) and as long as the one that is required is there, you add the specified amount of raw materials and CRAFT again?
