Almost all number fields in the game are auto-filled with the full amount available. Country Store, Workshop, Wishing Well, Farmer's Market, Steak Market, etc., and it works beautifully.
But the Feed Mill is auto-filled with just 1, when you go to select which crop to feed it. I would like for it to also be auto-filled with the full available amount. If not, a +MAX button like there is in the Flea Market would be so, so appreciated.
