OK, so the View Cube provides free rotation (reduntantly to Shift-MiddleMouseButton) and ortho and iso views. But sometimes it is necessary to define other views and to have them exact. I might need to create renderings of two parts viewed from exactly the same angle. Or a drawing view at a particular angle might show the feaures better and I want the verticals to stay vertical in the drawing. I have found no way to do this in F360.
So how about adding to the View Cube drop-down menu:

The three angle could be called Compass, Pitch, and Roll or something like that to sound more tech. Basically they are just exact manual inputs equivalent to drag rotations. They could have sliders but these are not really needed if the boxes always show the current angles. Just drag the part or assembly to roughly the right angle and then adjust the values in the boxes to set the exact angle needed. Set the "twist" angle to zero to keep verticals aligned vertically.
The focal length adjustment is really an additional option and maybe adds complexity to the display code. One other useful option would be a Named View box that is initially blank. Fill it in to get a named view without an extra step.
