Additional Inventory(Backpack)

We should have a inventory extension. I have encountered many times where I did not have enough inventory slots. The backpack could add 20 more inventory slots and the player could wear it instead of a chestplate. It could even carry one tamed animal like parrots, wolves, cats, and foxes. It can also provide little armour points(provides 1 armour point). It can have different skins, for example, red and black, blue and yellow. It could be crafted out of hide, string, and lead. The backpack also should be placeable and you can leave it anywhere, so it is like a portable chest that you can take on or off. However, other players or specific mobs(zombies, skeletons, spiders) can take your backpack and you cannot get it back unless you defeat them(or for players' case, take it off). It can be found in villages, ocean monuments, abandoned campsites, woodland mansions, pillager outposts and more. The picture is generated by AI but the ideas are my own. I really hope Mojang will add this
