There is one feature I think could be great to have in the inventory: Acces to shulker boxes without placing them. althoug I don't think it should be from scratch for it to not be too op.
So i was thinking, maybe we could have an enchant for the pouches and get this this way. Maybe for balance limit to the non upraded ones or the non upgraded snatchel so only 6 or 9 shulker boxes can be accessed maximum.
I can see this enchant beeing found in ender city too.

Could you please teach me how to make the bag, what items to use?
