Stackable Item
by quillphen
Stackable Item raises the stack limits of potions, boats, saddles, totems and other items so that a player's inventory holds fewer slots of them.
What it does
The mod covers potions, boats, chest boats, minecarts, utility items such as saddles, name tags, leads, bundles, totems and goat horns, food including cake, honey bottles and stews, projectiles like snowballs, eggs and ender pearls, and signs. Stacks grow from the vanilla sizes so that these items group together in a chest or hotbar slot.
Items with variant data keep their effects and contents. Potions, tipped arrows, suspicious stew and goat horns are not merged unless their data matches.
The mod runs on Fabric, Forge, NeoForge and Quilt and is also available as a data pack. Files cover 1.20.5 – 1.21.11 and snapshot builds are published. Stackable Item is released under the GNU Affero General Public License v3.0 only and is not open source. The server must run it, while clients may leave it out.
Key features
Larger potion stacks
Potions, splash potions, lingering potions and tipped arrows stack further, while keeping their individual effects.
Merged boats and minecarts
A second boat or minecart picked up merges into an existing stack instead of taking another slot.
Bigger food and projectile stacks
Cake, honey bottles, stews, snowballs, eggs and ender pearls group into larger stacks.
Consolidated inventories
Items already in a player's inventory are combined automatically, unlike stack-size datapacks that only change limits.
