It is sometimes desirable to have a joystick snap back to the zero
position.  It is also sometimes desirable for it to stay where it is
without having to hold it.  Can we have both?  What about a locking
joystick-- A spring-loaded joystick which also has a mechanical lever
or knob that can lock the joystick in its current position.  Perhaps
if crafted right it can have variable resistance, so that one setting
counteracts the springs but still allows the stick to be moved by
hand, and a tighter setting more solidly locks it in place.
