Hi, over at the fire place mod i got a request to merge with this great mod.
So to make things easy I added a cooking recipe category which is used by the camp-fire.
Would you like to make i_i happy and introduce the cooking recipe category to your mod as well?
But I think the crafting_categories updating part should be part of data-final-fixes.lua to update even modded furnaces.
And thinking about it, maybe you want to introduce a way to filter furnaces, so maybe not every furnace has to cook ;).
