I propose to add inline comments for the following reason:
General understanding is promoted when reading the source files as probablyt the main entry point for a developer.
js,css,qweb are taken from other manifests I've seen. They are explained in the link. I think completedness of the manifest scaffold also helps reduce ambiguity about it.
Lastly, I introduced newlines for better readability and grouping.
I hope these changes, well (marginally) improve the usefulness of this great module.
