Multi Bags - new cool backpacks на версии [1.12.2] [1.16.5]

This is a mod for very convenient backpacks that can hold a lot of items. There are several types of backpacks, for example, diamond and emerald! This backpack can be worn on the back, in the hands, or placed on the ground! It will be extremely convenient because it doesn't need to be opened separately, as it adds a new interface in the inventory and increases the player's number of slots. This interface is visible not only in the inventory but also in furnaces and chests!
