Better item switching on Mobile

Why we need better Mobile item switching:

We need an easier way to switch items in the hotbar for mobile because if you are in PvP, you need to switch items sometimes and there are other reasons to have easier item switching on mobile. All that we would need are two more buttons with all the others, maybe a little smaller, above the rest, that will switch items in your hotbar left ot right and maybe you could even add a third button for the inventory. It is such a hassle to switch items on mobile minecraft, so we need a solution.
