OFF HAND!!!

Mojang, here me out, A main feature on java edition is off hand and the reason why it is not there in bedrock is because of mobile players like me BUT YOU CAN ADD!! In a update, they added new controls for mobile and one of the most popular one is one with the interact button, you can add an other interact button(2) to CONTROL THE OFF-HAND!!! IT IS IMPORTANT FOR THE GAME AND FOR OTHER CONTROLS (WITHOUT SPLIT CONTROL) LEFT SIDE IS FOR OFF-HAND. Without that we are crying:( Now this will make everything easy like building etc. PLS PLS PLS PLS PLS:(
