Xinput was planned in the beginning, but did not make the cut. Over time more people desired it and I do as well. When it is on list of features to implement in whatever update it ends up coming in I would like to ask if not only thumbstick tilt analog movement is included, but also other buttons on a xbox controller like A and X for regular clicks with the addition of triggers that could also work via deep click(If this was not already the plan).

Another output which might seem strange, but I definitely find it useful in my testing for CAD is analog tilt for mouse movement. JoyToKey does this well by converting joystick/controller behavior to mouse movement, I can move my entire mouse to smoothly with variable speed to free-rotate an object.
