"To hardly have vertex normals tools in Maya is simply ridiculous.
We need:
A tool able to replicate... er... last vertex normal selected.
A tool able to average normals. Let's say, pick up some vertex normals, and apply average to last one.
A tool to make real planar faces into real planar faces. This is, no more "rounded borders" surfaces with a transition of normals from a side to the other.
Vertex normals needs documentation and learning."
