About this project

What does Extended Stacks add?

📦 Extended Stacks

Extended Stacks is a simple but highly useful mod that increases the maximum stack size of items.

Instead of the default 64 items per slot, you can now store up to 99 items in a single slot.
Items that normally have a limit of 16 (such as eggs, snowballs, etc.) are also expanded.

🔧 Features:

  • Increases standard stack size: 64 → 99
  • Increases small stack items (16 limit): 16 → 99
  • Works with most items (unless restricted by the game itself)
  • Keeps the gameplay balance mostly vanilla-friendly

💡 Why use it?

  • Less inventory clutter
  • More efficient storage
  • Better quality of life without major gameplay changes
    (ps. this mod has a 1 joke this is april fools mod)
