LoxyStackTweaks
by CallMeLoxy
Vanilla items that cap below 64, including Ender Pearls, Snowballs, Eggs and Signs, are raised to 64 by LoxyStackTweaks, which lowers how many stacks a player has to carry.
What it does
Empty buckets stack up to 64 with the mod installed, and vanilla items that currently stack below 64 are normalized to 64. Filled buckets stay protected by default, as do items with durability, maps, books, bundles, shulker boxes and stacks carrying custom data, so their behavior does not change unexpectedly.
The mod is a Fabric-only addition for 1.21.1. It needs Fabric API and runs on client and server, so the server and every player install it. Files are on the Fabric side only, and the mod is released under All rights reserved, so it is not open source. Its configuration file is generated on first launch, and a reload command applies changes without restarting the game.
A configurable whitelist and blacklist govern compatibility, and a forceToOne list keeps risky items from ever stacking. The mod is kept focused on quality-of-life stack changes and avoids inventory behavior that could cause loss or duplication.
Key features
Vanilla stack normalization

Protected risky items
Filled buckets, items with durability, maps, books, bundles, shulker boxes and stacks with custom component data keep their default limits.
Whitelist and blacklist
Configurable lists let server owners include or exclude specific items, and a forceToOne list keeps risky items from stacking.
Reload command

What the author says
LoxyStackTweaks is a lightweight Fabric mod that safely improves Minecraft stack sizes without blindly forcing every item to stack. The mod normalizes vanilla items that are already stackable but limited below 64, such as Ender Pearls, Snowballs, Eggs, Signs and Hanging Signs. Empty buckets can also stack up to 64.
