Another thing needed is turning deceleration. With 0-100, 0 being "never turns, just keeps on going forever", and 100 being "turns on a dime."

The Joystick Controlled behavior needs improvement. GamePress' Joystick Controlled behavior was great. With HyperPad, even with deceleration at 100, it takes forever to come to a stop. I suggest using the deceleration feature as: 0-100, 0 being "keeps on going at the same speed forever", while 100 is a "stops instantly."
