When displaying the planets in the right hand pane some favourites related to the solar system are appended to the planets list. Under "User Favorites" some of the JPEGs with the word "planets" in the name are included, but none of my favourite SNF files are listed.
P.S. I've modified the planets display to match my SN6P display so it may look a bit funny to you. "Factory Reset" won't restore the original look.
