Seriously if you dislike the mincromanagement, just support the idea of packing 40 units of food into 1 Camp Supply ...
By right clicking on any food in your inventory.
With the current abundance of food in the game I'm surprised short rests are free. Surely like a 10-15 supply cost for a short rest, and forced 2x short rest before long rest unlocks leading to a total of 70 supply cost for a day.
What does it change, except raising amount of supply cost per Long Rest to 70? O_o
