Major and Minor Axis show while sketching an Ellipse? A "Nice to Have"?

Hello! Just wondering if anyone thinks this would be a "Nice to Have" update? The major and minor axis of an ellipse are automatically created as the ellipse is drawn in a sketch. (As construction lines?) Use these to orient the ellipse and have vertices for a loft.

    Hmmm I gave some feedback via the question mark on this too as adding relations to restrict the angle requires construction geometry at the moment i believe, I'd prefer anything like that to be optional as per rectangles in SOLIDWORKS  as i dislike visual clutter and that seems to be a focus for Onshape too. For me i'd like to hover over the ellipse to see its axis and then be able to easily set it horizontal or vertical by picking the axis/centre. Certainly would be nice to be able to add the centrelines easily though as i do find myself adding them quite often in SOLIDWORKS also when i want to set an ellipse at an angle for some more complex parts.

    As I said, a "Nice to Have". That was one of the update classifications back when I was inside Caterpillar when they brought Pro/E onboard. Maybe it could be a "User Preference" setting or a "Check box"/"Pull down menu choice" in Sketch. Every time I have drawn an ellipse I have needed an axis line to control the angle. Hmm...maybe there is an "inferred" horizontal when sketching. I must "unlearn" some things at times!

    Solidworks and OnShape models cylinders cut at an angle as ellipses; And cones cut at an angle as ellipses; Cylinders have 1 axis, and a cone cut at other than a right angle to its axis forms an ellipse that has two 'virtual or possible axes' that get farther apart as the angle gets farther from a right angle, one of the two points coincides with the axis of the described cone (sometimes called foci, the two focus points of the ellipse.) We vote for this addition as it is a stepping in point for trying the waters of geometry on earth!
