... Preview Vertex Maps?

The most effective way to preview a vertex map's influence is to render the mesh, because only this method represents the plugin's “Scale” settings.

 It is also possible to make the currently loaded mesh editable. Of course, this action will bake the active state and you will lose all of the plugin's features, but the vertex maps will be stored. Just click on a tag and you will see a colour gradient covering the mesh.
