Star/Favorite a Page
Users can "star" a page, thus marking it as a favorite.
Marking a page as a favorite can be done by clicking the star icon that appears when you hover a page on the Page List.
Or directly when viewing a page, using the star icon on the page actions
Favorite pages show a solid star in the "Starred" column of the page list, and you can easily fitler the page list for favorites using the filters dropdown.
To unfavorite a page, simply follow the same steps, and click the favorite buttons again, and the page will be removed from your favorites.
Favorite pages are stored on a per-user basis, giving each user their own list of favorites.
