Reorder The Hotbar is a mod that allows you to customize the order of the items in your hotbar.
Simply drag and drop the hotbar slots to rearrange them to your liking. This mod also adds the ability to click on the hotbar slots as an alternative to pressing the hotkeys.
So, you want to slay zombies while wearing a bunny outfit, but you don't want to give up your Firefighter outfit's protection? Do you want to wear that nice Military Jacket, but the protection stats are less than your Leather Jacket?
