Inventory Space

[waylaid]

The UI does not need a change, it looks exactly how the devs have programmed it to look. It is not empty slots, it is a specific design choice by the devs. If you use the expanded inventory, you'll notice that all of a sudden the Key Items tab now has extra "space". That space didn't come from thin air, it's not extra inventory, it is simply there to make it look the same as every other page in the inventory.
