Historically, the main purpose of SF Archiver was to allow users to simply add links in the menus to any Custom Post Type archive. 
Since WordPress 4.4 adds this feature, it has been removed from SF Archiver version 3.0 (see the “Developers” tab for older versions). Still, SF Archiver provides some other cool stuff:
<ol>
<li>Set the number of posts per page to list for each post type.</li>
<li>Quickly visit your archives by using a handy link in your administration area (in your posts list, see the icon between the title and the “Add New” button).</li>
<li>Small quirk: when displaying one of your Custom Post Type single, “highlight” the corresponding archive menu item (WordPress does the same for the Posts when they are not displayed on the front page).</li>
<li>Small WordPress bug fix: WordPress wrongly “highlights” the Blog menu item when a Custom Post Type single or archive is displayed.</li>
</ol>
