What can it do?
It helps players quickly calculate required materials for bulk crafting. It provides persistent on-screen material lists, detects items in shulker boxes, supports multiple preset slots and display styles, integrates with JEI to view recipes, and allows key binding customization.
How to use it?
Use a configurable key (default: U) to open the calculator, view a recipe in JEI, and click '+' to auto-import the required materials into the list.
