Suggestion: Disable stacking for melons and dried kelp blocks
Currently, melons and dried kelp blocks are able to be stacked to 64. While this has always been their behavior, both items were added after the hunger overhaul, and they allow for far more food to be carried than was once typical.
With a stack of dried kelp blocks, a single inventory slot can store 576 health, equivalent to carrying 72 cooked porkchops! A stack of melons may provide even more health, depending on your luck when breaking them into slices.
To preserve the old balance of managing your food on hand, I recommend that the stacking of melons and dried kelp blocks be disabled (when food stacking is disabled).
