❓ Why This Backpack?

Traditional backpack mods = mobile chests requiring separate GUIs. Our solution:

1. Seamless experience - Access backpack items directly in work GUIs
2. Native interaction - Full support for recipe book/JEI/REI/EMI
3. Backpack swapping - Swap when placing backpack in backpack slot/inside
4. Continuous expansion - Growing mod compatibility support
