Hi Kevin, Thanks!

There is a brief description of the new on-surface drawing here:

But you should probably get the hang of it pretty quickly, it just kicks in automatically if you snap your points on to an existing surface while you are working in the 3D view.

If you pick points in the Top, Front, or Right views it will not kick in - things will still align to those planes while working in those views, it is just when working and picking in the 3D view that it will kick in.

I'd certainly be interested to hear if it provides what you needed for workplanes or not!

The idea there is all about providing some of the basic functions of a construction plane in a quicker and less formal way.
