Pocket edition touch controls (Customizable)

I think you should be able to create your own controls for the touch settings, mainly because I like Joystick and & Aim crosshair but it is really hard to move. so i think we should be able to merge/create our own controls. For example we could have the D-Pad movement controls but have the aim crosshair. 

I find it hard to move when using the Joystick because I have used the D-Pad for so long but i also like how it doesn't take as long to break/place blocks in creative with the aim crosshairs, since using my fingers to hold down to break blocks when im trying to build always irritates my fingers, but i find it easier with the break and place block buttons. 

Please add more customization for mobile players!
