Hi Paul, well it would be tough to add handles on to every point in MoI. MoI uses NURBS curves, if you turn on the points for a single curve segment, you'll see that only the start and end points are on the curve. All the other interior points are not directly on the curve, so it would be hard to add handles on to them...

Bezier curve editors that focus on that type of handles actually break curves up into a whole bunch of little segments, with each segment made up of 4 control points. When you edit the handles between 2 segments in a non-symmetric way, that maintains tangency between the pieces, but actually breaks a different kind of smoothness between the pieces (curvature continuity).

That kind of smoothness break isn't that big of a deal for 2D outlines, but as you create 3D shapes that kind of break can start to become more noticeable especially in shiny highlights or reflection lines.

It is hard to do a handle-style editor without breaking this higher degree of smoothness...
