"Hit/Break block" & "Use/Place block" that have custom layout

"Hit/Break block" & "Use item/Place block" buttons can be very very useful for mobile users for pvp servers and even single play because I'm sure most players are struggling with the way of hitting players and destroying blocks and this can be very very useful. Ohh, you should also add an option to customize the layout of all buttons, it's size, and it's shape. Please add them! Im sure most of minecraft pe players will love it Sorry for my bad English because I'm from Philippines 😅
