Pocket Backpack!

Your pocket, without the door. The **Pocket Backpack** is one item for Pocket Door players who are tired of carrying
and placing doors: right-click it anywhere and step straight into your pocket; use it again inside and you are back
where you stood. Press **P** and it works from anywhere in your inventory, or from a Curios / Accessories back slot.

**Wear it.** Put it in a Curios or Accessories back slot and it shows on your back, portal and all (1.21.1, 26.2, 1.20.1).
With Curios installed the mod adds the back slot itself, so nothing else is needed to unlock it.

**It plays by Pocket Door's rules.** If you live in your team's pocket (`/pocket use team`) or a friend's, that is where
it takes you. Locked and banned pockets stay shut. Pets, leashed animals and your mount come along. From the Hub or
someone else's pocket it takes you home.

**Balanced for packs.** Out of the box, entering starts a one-minute cooldown, leaving is free, and it won't open for ten
seconds after a fight. `pocketbackpack-common.toml` (1.12.2: `pocketbackpack.cfg`) lets you set the cooldown and whether
leaving counts, an opening delay that a hit interrupts, a combat lock, an item each trip burns (ender pearls, anyone?),
dimensions where it never opens, one-way use (in only, or out only), sneak-to-use, and whether the key works at all.

**Recipe:** 

**Requires Pocket Door** 1.10.1+ (Minecraft 1.21.1 and 26.2) or 1.9.1+ (1.20.1 and 1.12.2).
Builds: 1.21.1 NeoForge, 26.2 NeoForge, 1.20.1 Forge, 1.12.2 Forge.
Optional: Curios or Accessories for the back slot (not on 1.12.2).
