Why aren't all extras displayed in heavy mode?

Question

http://wiki.smugmug.net/display/API/show+1.3.0?method=smugmug.albums.get

Why I cannot see the following extras in response

• SmugSearchable boolean (owner)
• SortDirection boolean (owner)
• SortMethod string (owner)
• SquareThumbs boolean (owner)

Answer 1

You are correct in your subsequent comment, any property listed on the API page you linked to followed by (owner) will only be visible to the owner, which will require authentication.
