Container Enchantments (Inventory management)

In my opinion the perfect way to tackle the inventory problem would be to add inventory-related enchantments that apply to shulker-boxes, pouches and enderchests, with off-hand functionalities.

Collecting Enchantment: Redirects all picked items into the Container. Filtered by already present items inside. If in the off-hand and crouched, all filters are bypassed.

Supplying Enchantment: Redirects all inventory interactions to the contained items. That means intead of placing the Container, you can directly place the next item in line. You can also rapidly drop items right from the container.

Off-Hand inventory: If you have a container with this enchantment in your off-hand, by right-clicking you can directly open it.
