The idea is not to select others bookmarks.
The idea is to have a homepage of bookmarks (featured topics) selected by admin(s). If you don’t like the term “bookmark”, you can call it “featured topics”. It is the same idea. A homepage can be selected which is composed of “selected topics” by the admins (versus the current limited set of options).
This idea, as I originally understood it, does not effect bookmarks by users (or anyone). So maybe the term “featured topics” is less confusing?
