PE D-pad redesig and crouching placement

I have come across many problems with the on screen controls for PE. One problem being you cannot strafe while walking backwards. I see two ways of fixing this. Fist being the insertion of strafe buttons on the bottom of the D-pad. But a problem with the D-pad itself is, if you slide your finger of the button you stop moving. Which you may have noticed, can be a problem in a combative situation. The second, covering both problems, is a joystick that keeps you moving no matter how far you slide across the screen. (Like in most mobile games) For sprinting you can use the same concept as used for console editions. Now with the redesign of the D-pad brings up how the crouch/jump button is not in the most convenient place. When it comes to sprinting you double tap the forward button, but if you’re off a little.. oops now you’re crouching. If you’re running from a Creeper... you know. I think moving the crouch button to a little farther up on the Left side of the screen would fix that problem.
