About this project
What does Stack Size Plus add?

Stack Size Plus increases the stack size of many normally non-stackable items to 64.
This helps inventory management while preserving item data rules. Items that contain data will only stack with identical variants (for example, purple wolf armor can only stack with purple wolf armor.)
