This regards the PC version. If a player has a crock pot and a fridge or salt box open at the same time and shift clicks on a food item in their inventory, the game will prioritize moving the food item to the fridge / salt box instead of the crock pot.
This prevents the player from quickly and conveniently loading up a crock pot by shift-clicking on food items in their inventory when the fridge / salt box inventory tab is also open. It also leads to cumbersome controlling since it's easy to accidentally move food items from the player's inventory bar to the fridge / salt box instead of the crock pot, which requires a lot of cursor repositioning when standing near many crock pots and cooking.
I believe this proposed suggestion would feel a lot more intuitive for players. It probably doesn't require many code changes to alter.
