     * Map containing page mappings that can be used to set the initially displayed page

     * the first is the list of main Preference categories (such as General and Display)
     * and the second is any sub-stack found on that page.
     *
     * TODO: this isn't the most optimal solution, since if the order or number of pages
     * in either stack changes, this map needs to be updated. Optimally the stacked_widget
     * widget would allow specifying page by string id, but that would require changes to
     * generator. It's something to look into, however.
