It would be handy to be able to select points from a dense point cloud and move them to their own layer. Then to be able to build a mesh on the same layer from the dense point cloud on that layer, and finally export an ortho image for that layer. This would be useful for cleanly separating elements of an object such as the sides of a structure or excavation square. The ability to toggle layers on and off would also help when selecting points and inspecting dense point clouds.
