Assignment adds a new column to the admin list for the content types that have assignments enabled. In this demo, that content type is pages.
The new column indicates if something has been excluded from assignments or how many testimonials it has plus a link to a filtered admin list of its testimonials (see the Testimonial admin list – filtered screenshot).
Assignment adds a filter to the testimonial view editor. The filter determines which testimonials to show. In this example, the filter adapts according to the current object (post type). In this demo that is pages.
