2.3.3 Favorite views
In most cases the user has to display some specific regions more frequently. The feature “Favorite views” provides fast and easy positioning of the map view and adjustment of the zoom factor over such regions. This function is similar to the Bookmarks function of the web browsers. The favorite views can be selected from the “Favorite views” drop-down list (Fig.7)
