Upgraded Player Storage
The Upgraded Player Storage mod adds an expanding storage system to your player inventory. It allows you to take a significant amount of items with you at all times but keep your main inventory free for only the items you deem necessary. It can be accessed when you open your inventory.
The inventory space defaults to allow you to carry up to 2000 extra items, and upgraded by eating a series of apples ranging from iron to nether star that can allow you to carry up to 2,000,000 extra items.
The mod also has a crafting inventory built in, and fluids section too.
