Hi Paul - well the W is a pretty obscure thing - it's just for polar coordinates centered at the origin instead of from the previous point, like w5<24 .

I was just thinking that I could pretty easily remove the auto-focusing for W because that world polar coordinate entry is just not going to be used very often, and it would still work if you clicked on that control first.

However in V2 when there is an option to relocate the construction plane to some other location, it will probably work well to use regular points to be in that relocated coordinate system, and have w as a prefix for entering world coordinates.

So I guess I will leave it so it can be leveraged in the future.
