SessionRestore works well on main-page tabs, but does not work well on the new Safari Groups feature. All tabs on the main Safari page get backed up properly, but the Group backups are haphazard. Some Groups get backed up, others don't--the Group names are saved, but the tabs in many Groups don't get saved. Also, tabs in some Groups get moved to the main page when restored, rather than to their proper tab Groups. Others don't. This app needs to be updated by the author, to work properly with the new Safari Groups.
