I need to rotate objects with precision, however, the orientation of the object changes frequently when clicking on the LMB and dragging since the mouse is a sensitive device. The object moves slightly up or down when rotating it. Keyboard buttons to turn objects around horizontally and vertically could be a nice addition (like rotate right, rotate left, rotate up and rotate down buttons).
You can use this at the end of the URL , change the value for what you want, use a “-” in front of the value for opposite rotation
unfortunately its only horizontal
but you could also do manual mouse movements using this trick here:
though bare in mind the less sensitive you make the mouse the less rotation or panning you can do before the mouse hits the edge of the viewer, its a pity the mouse dose not wrap around when rotating/panning
