This release (v.03) dynamically removes the auto-detected search engine when the user navigates to a different web site unless the user selects the "Add <Search Engine>" menu item from the searchbar's list of available engines to install the search engine. For example, the auto-detected search engine is dynamically added and appears as the current engine when the user navigates to a site with an OpenSearch plugin. The dynamically added engine can be used immediately to search the site without the user having to manually "Add" it. When the user clicks the searchbar's button to display the engine list, the dynamically "Added" search engine is then put on the list of engines as an "Add <Search Engine>" menu item . At that point, the user can choose to manually "Add" the auto-detected search plugin and it will remain on the list of installed engines when the user navigates to another web site.
