This script is a must have for medium polygon modeling.
Weighted Vertex Normals or Face Weighted Normals use the area of the face to tune the vertices normals.
This script does this for you with just one click.
Unlike others FWN Scripts, this one considers coplanar faces like they were a unique big face
You can disable this feature to get an standard FWN result, or increase threshold for not completely flat surfaces
