Maybe add support for small and large boxes and fridge as well?

Hi,

I see the single option to implement -- sort the food on a campfire/barbeque.

Sorting within other containers doesn't make much sense.

Something like https://umod.org/plugins/quick-sort but simple

Sorry its another plugin, Active Sort is closer to Furnace Sort, but not for item sorting. Active Sort splits item stack into as many as possible parts to increase melting speed.
