Specialized Inventory Slots

A big issue with inventory management especially with the hotbar is that a lot of slots get taken up by items that you "need" and typically will always stay in those slots since you "need" them most of the time. This was partially addressed by adding the off-hand/shield slot which helped, but didn't fix the issue.

So we need more slots that are meant for specific items.

- Like a slot just for the Elytra So that we can wear a full set of armor and Elytra wings,

- A slot for a quiver that could hold a few stacks of arrows or just a slot that holds only one stack of arrows.

Next ones are a little more crazy ( have the problem of likely needing more key bindings to be added)

- A separate slot from the off-hand slot for the shield, so that when caving we don't have to choose between lighting up the cave and protecting ourselves for mobs. and so we could hold enderpearls, totem of undying, etc... in our off-hand while still being able to have a shield.

- A slot for the Bow, Crossbow, and other projectiles(like enderpears/snowballs). so that you can switch between melee and range while having more room on your hotbar. I know this would likely add the problem of adding more key bindings which i think Mojang is trying to avoid since they have to keep console and phone players in mind.
