About this project
What does Stack Size Tweaks add?
Stack Size Tweaks
Stack Size Tweaks increases the default stack size of items for a better survival experience.
It let's you change stack sizes up to 1 billion using the config.
Default Stack Sizes
Categories are ingredients, blocks, food items, items that normally stack to 16, stews, potions, filled buckets, enchanted books and discs

Font
Stack Size Tweaks includes a custom font that only renders inside the inventory (enabled by default).
It makes higher values inside the inventory much more readable alongside the formatting.

Config
This mod has a config where you can adjust the stack sizes for different item categories and specific items.
Editing max stack sizes requires a restart to take effect.
Access the config by using Mod Menu or NeoForge mods sreen or editing the stacksizetweaks.json5 file in the config folder.
