Nice little app that helps the user recall the numbers of the buttons. This can be helpful when creating profiles for games and you want to assign a button to a function but you cant remember the number and at the same time test if the buttons, axes, and hats are working. I tried it on my Saitek X-52 Pro and it recognized the joystick and all its functions. My wish: I would like to see an update for this app with a TEST button that you click and it colors everything red and when you press or move something on the joystick it will color the corresponding number in green so you know that the button you pressed is working. Anything that remains in red would mean either it has not been pressed yet or is not functioning properly. This way, you can report which part is malfunctioning in the joystick to the manufacturer or dealer.
