I'd like to see a visual difference between a corner point and a smooth point. Both have very different attributes, but they look the same.

Maybe an option to set corner points to a square, or a different color, or some type of indication without opening a panel or running a script.

Examples:

Corner points in construction curves can cause unwanted behavior in Lofts and Fillets. I try to construct curves in the simplest way possible and only use corner points when needed. But they can appear when making a Mirror, and it would help a lot to see them at a glance.

Sometimes I want a corner point in the middle of a curve so a seam gets created. This allows me to assign two colors to the same curved object. Again, I can't just look at a curve and see the difference.

A bonus would be to have the ability to switch from one type to another by double-clicking on the point.
