+1 To further back up Soares's point, I use my Xbox controller linked to my phone to play this game sometimes. The controller acts as a keyboard in this function however the buttons; LB/RB/A/X/B/Y/Start/Select. If they were to just add a function to allow the D-Pad to be key-binded would be a game changer, and if possible, movement on the sticks would be great!. The fact is people already use external controller sources means that PRO must have a pretty good detection system, so allow more flexibility for the current users. I'd like to think if people were using external devices for turbo movements or it was an issue worth raising, they would completely void the function to allow other keybinds and just stick to keyboard/swipe tap option for handhelds.
