Belts

Think of how annoying it is to decide weather to use a shield or a totem in the offhand? I got a idea what if Minecraft added Belts. They can hold up to 3 items. It would be set so when you hold alt you can shift through the options and choose one. So now you can have a shield in your offhand, and then lets say a totem, food, and fireworks. Just use your shield though when your Hungary hold alt, scroll through and get the food, after you let go of the item like food for 2 seconds it will replace the offhand with the original item. Then when your about to die the totem on your belt will auto activate! same thing for the elytra's! The belt can be attached to your leggings in a anvil.
