Costomize Button Idea, And remove or expand the costomize control border

I have an idea that try to make the chat button, pause button, emote button, and effect ui button costumizable like other action button and we need mojang to remove the costumize control border area. We mobile players have a little screen and not all Minecraft players are rich that can buy some accessories like controller and mini keyboard and mouse to add on their phone. Ive like pvp in bedrock/pocket because its different in java so i find an idea to make my game more comfortable with costumize control and can keep up with pc or consoles players, but im lose hope because the border not extended to place my game accessories like mini clip button triggers, i buy that for 2 dollars but i lose hope because i cant use that in top landscape of my phone because the border cant reach it. And i came up with this idea that i wish mojang notice and add this on mcpe soon... Pls mojang im begging,. But warning i have no intention to change the game in what i want, im just saying an idea because we all mobile players are so struggling at the game like i cant fight or keep up with pc guys and this idea might be help to expand our screens like it makes more widely to swipe, drag, and click. But im begging for this idea to mojang need to see
