In using the Joystick to manually find the Sun or the Moon, quite often we are pretty sure about where they lay on height (because Seestar being leveled), but not so much on azimuth. But it's dificult to move the Joystick ONLY in azimuth, so quite often it also moves inadvertedly up or down in height, making it harder to find the object. It would be nice to have some lock feature to allow user to move freely on one drive only for those matters. Many thanks!
