How is this different from the 'Visibility' check box that already
exists?

When you turn the visibility of the widget off, then mouse movements
will not affect the 3D widget. Can you elaborate on the functionality
that you want that's not provided by the current check box?

It should also be noted that any GUI changes are going to be extremely
low priority at this point (with ParaView3 in the pipeline).
