Shortcut to change perspektif in the minecraft mobile(phone)

This shortcut is just a simple idea, and I don't know if someone else is already thinking about this too, but here is my suggestion. My idea just use a paper doll feature as a shortcut to change perspectives from( First Person to, Third Person Back to, Third Person Front ), with just one tap on the paper doll, you could cycle through perspectives (1st → 2nd → 3rd) and then back to the 1st person view again. For me, this is good. You know, on mobile, we can't just change the perspective with a button. We need to go to the menu first, and that is really slow. It makes the gameplay not seamless, even if it's just for a second.😆 Sorry for my English so bad
