Opening and wearing in Inmis

There are three ways to open a backpack:

• Right-click it while holding it.
• Press the key bind (default B), which opens the first backpack it finds on you — including one worn in the armour slot.
• Right-click the ender pouch to open your ender chest instead.

A backpack can be placed in the chest armour slot. Worn like that it renders on your character's back for everyone to see, and it still opens with the key bind, so you get storage without giving up a hand or a hotbar slot. Whether backpacks may go in the chest slot at all is a config option.
