Here are its some of its features
Nestable – Backpacks can be used from inside other backpacks
While a backpack is opened it can’t be moved, so there is no chance of accidentally putting a backpack inside itself.
If you are holding a backpack when you open a chest it will open a multi-sectioned version of the chest interface that you can open backpacks from, allowing you transfer items between backpacks and chests.
Accessible – Backpacks can be accessed from almost any GUI
You can also open the ‘full’ backpack interface by shift+right-clicking, but doing so will replace the current GUI.
The ‘lightweight’ interface is adequate for most tasks, but if you need to upgrade, rename or recolor your backpack you’ll need to open the ‘full’ interface
Customizable – You can change a backpack’s name, color and size
Each backpack pouch will add 9 slots to the backpack, up to a maximum size of 9×8.
If you are in creative mode you can freely change the size of a backpack by using a ‘Backpack Resizer’.
Safe – Lost or destroyed backpacks can be recovered
Backpack Restorers can be expensive and they only restore one backpack each. So if you lose your backpack often you may want to invest in a “Quantum Chest”. Simply put your backpack inside a quantum chest and it will start dispensing “Quantum Backpacks”.
Quantum backpacks are bound to the quantum chest they came from, and can be used to remotely open the backpack stored inside it.
The quantum chest allows you to take as many quantum backpacks as you want, so if you die, or if you just want another quantum backpack, you can just go back to the quantum chest and take another.
Shareable – You can share your backpacks with other players
Any changes made to a backpack by one player will be updated in all other players using that backpack, allowing players to share or exchange items no matter how far away they are (or what dimension they are in).
Protectable – You can prevent players from using your stuff
Simply press ‘p’ when you have a backpack or quantum chest open and you’ll bring up the permission interface, where you can change who is allowed to use it, who is allowed to add or change permissions and who ‘owns’ the backpack/chest (defaults to the first player who opened it).
Pressing ‘p’ from a permission interface will bring up your own permission list which allows you to see all items you have permission for and can be used to change the permissions for items you don’t have access to (like if somebody stole your backpack).
If a player is ‘opped’ they can choose to bypass the protection on chests and backpacks.
Automatable – Backpacks can automatically collect or resupply items
When a tool breaks or you run out of a block that a backpack ‘resupplies’ a replacement will automatically be taken out of that backpack (provided it has one).
You can configure what items a backpack will ‘collect’ and ‘resupply’ by pressing the ‘Edit Backpack’s Auto-Loader’ key while a backpack is open (if the toggle button says ‘Only’ the backpack will collect/resupply any item included in the list, if it says “Don’t” the backpack will collect/resupply any item not included in the list).
Pressing capslock while the collect/resupply interface is open will lock or unlock that backpack, if a backpack is locked it will only accept items it collects.
Placeable – Backpacks can be placed by shift+right-clicking the side of a block
Items a backpack collects can be piped into the top of a placed backpack, items it resupplies can be piped out from the bottom and any item can be piped into the back.
Using an Eye of Ender on a placed backpack will duplicate the backpack, allowing them to be used like portable Ender Chests (If you need more than 3 copies of a backpack it may be cheaper to invest in a Quantum Chest).
You can prevent pipes/hoppers from interacting with your backpack by using the permission system to deny access for a player named [world].
