It would be really beneficial if we could have an option to implement and adjust joystick analog input (axis) filtering.
Main goal would be averaging (smoothing) input signal when someone is using more or less worn joystick, which potentiometers manifest spikes in signal.
I guess such a feature wouldn't be too difficult to be implemented and added in axis tuning screen. From experience I know it would be very useful and welcomed by a great number of players.
