BiggerHotbar

This mod works entirely on the client side!

With this addon, you gain the ability to use the bottom row of your inventory as nine additional quick access slots. You can smoothly switch to a virtual second hotbar, where items are automatically swapped, but visually nothing changes.

It creates the impression that you're directly using items from your inventory on the main quick access panel.

The modification remembers the correct placement of your items, so you don't need to worry about your inventory being disrupted when leaving or joining a world or server.
