Increased inventory for late game players, mapping and enchantments

I think  a new enchantment like swift sneak only found in the deep dark called 'deep pockets', three levels of extra inventory and like swift sneak can only be applied to leggings. Each level up to level 3 gives nine extra slots of inventory. Shulker boxes help a bit but they need to be placed down to access. With the increasing number of items in the game I think this would help.

I would also like to see a way of organizing maps, perhaps combining with a book and quill to make an atlas with an index for easy reference to required map.

multiple enchantments on items should also be able to be selected and removed without disenchanting  the entire item. Enchanted items should be able to have their enchantments transferred to books in the grindstone perhaps.

Thanks
