It would ge great if users could move/drag shapes (lines, polygons, etc.) drawn in ArcGIS Earth across the globe. Two simple educational examples: move the (rough) shape of South America to the east to align it with Africa. Or to move/drag the shape of New Zealand over Italy, to see the difference. Yes, you can do it by other means in 2D, but there, most likely, you'll have to account for differences in projections, while in ArcGIS Earth, it's like doing it on a real globe! Unfortunately, Google Earth doesn't do it either.
