I have map views with a large amount of marks. Users can use the zoom tools to view a section of the map in more detail and view individual map marks. I want users to have a way to return to the default map view (e.g. world map or map of the U.S.) without the hassle of backtracking through iterative zoom and pan steps. Is there a way to create a view as the default view that the users can return to with a single click or similar action?
