All writers, in all viewpoints, must choose which information and scenes will be presented, and in which order. In that sense, the author is always represented as a point of view in a work of fiction. His hand can always be detected by the discerning.

Novels have much more space than short stories, which gives you more leeway with the number of characters you can include. Even 'furniture' characters can be described and given speaking parts to develop background or atmosphere.

Words change over time. 'Condescending,' for instance, was once a good thing to be. It meant that a person was willing to interact politely with people of lower social ranks. In Jane Austen's world, a lady praised for her condescension was receiving a sincere compliment.

There are writers whose first drafts are so lean, so skimpy, that they must go back and add words, sentences, paragraphs to make their fiction intelligible or interesting. I don't know any of these writers.
