Better Stacking

Better Stacking is a simple mod that eliminates the inconsistent stack sizes in Minecraft.

automatically standardizes stack sizes across all items, including modded items:

Non-stackable items (beds, armor, tools, potions, etc.) → Now stack to 64

16-stack items (signs, ender pearls, snowballs, eggs, etc.) → Now stack to 64

64-stack items → Unchanged

Works with ALL mods! Any modded armor, tools, or items will automatically follow these new stacking rules.

Only issue with this mod is when you right click equip a armor in your hand it wont equip as a stack, i can't fix this sorry.
