Well as first part this I think should be better in the Feedback forum ?
About the new tools I have to say this need a better 2D focus, and as in the old BSP thread was said need the 2D tools extrude and scale faces without select it and move the mesh in the same way without select it just click in any part of the in of the mesh, and to to scale click and drag in any part outside of the mesh, that is how the fast workflow should be, I like a fast BSP system rater than modeling tools into the engine.
As second part I don’t notice auto UV or lightmap generation ?
