Sorry to post here -again . Could not find a way to post in feature requests. Was watching video below again.
Its a pity a subdivided re-topology surface information cant be projected onto the voxel/surface mesh to help smooth the surface in real time. "Area smooth" rather than brush smooth Hope you understand what I am thinking . Using a brush to smooth the surface wont give you a polished car body surface. I have a scanned mesh I need to clean and make beautiful. I posted an idea of a smooth "cage" but this might be easier to implement. maybe it already possible?
