Merge Stacks

Merge Stacks
Merge Stacks combines nearby matching dropped items and farm mobs into compact stacks, reducing the number of entities scattered around your world.
Dropped item piles can hold more than 64 items, while inventory slots, crafting, and normal item stack limits stay vanilla.

Features
Dropped Item Stacking
•Merge nearby items that have the same item type and components.
•Store up to 2,048 items per ground pile by default.
•Collect items in normal inventory stacks.
•Display the item name and total count above each pile.
•Keep differently named, enchanted, or damaged items separate.
•Control which items can merge with a whitelist and blacklist.
•Non-stackable items are excluded by default.
Farm Mob Stacking
•Merge matching chickens, pigs, cows, and sheep by default.
•Store up to 64 mobs per stack.
•Keep babies separate from adults and preserve supported variant differences, including sheep color and sheared state.
•Killing a stacked mob drops loot for one mob and reduces the stack count by one.
•Feeding a stacked animal separates one animal for normal feeding and breeding.
•Shearing stacked sheep separates one sheep for shearing.
•Stacked chickens produce eggs for the mobs represented by the stack.
