Hi, by navigating do you mean transforming objects?
You can click and drag an object to move them, if you click near an endpoint, the snapping will origin from there.

Apart from the bounding box controls transformations usually involves a command and two clicks.

I have exactly the inverse feeling towards gizmos; why can't I move/scale/rotate from here to there!
Transforming the origin appears more complicated than this method.

I guess each way has it's advantages, but in a Nurbs modeler like Moi precision and snapping comes to mind.
I learned solid modeling before Poly, so I imagine that make me biased a bit!
