Agreed. You could also use food to craft a supply pack, but it would need certain amount of certain foods to do so, like, 4 fruits, 4 vegies, 4 meats, 4 drinks, something like that.
I'm not 100% sure it would be cool but yes, thats something I had in mind. At least it's interresting and allow to think deeper.
Ragnarok's idea would just add a few more clicks to the current system without changing or improving anything else.... which doesnt seem interresting at all. Better not doing anything than this...
