When putting a stack of a carcass in the ingredients, it should work just like putting 1 carcass in (at least once you have learned the recipe). It seems extra tedious to shift click each stack, grab exactly 1, and put it into the recipe box, then dial in the number of carcasses at the bottom. I just feel like this can improved a little for a more pleasant experience. Another weird thing is some stacks peel off 1 at a time, and other don't. And sometimes it matters if deco mode is enabled. But just being a little friendlier with the handling of stacks would go a long way.
