Netflix has been tinkering with the organization of its site for years (not to everyone's satisfaction), and the content delivery service is mixing things up once again by splitting its "Watch Instantly" tab into separate "Movie" and "TV" sections — currently, "Just for Kids" is the only tabbed subcategory. The redesign is being tested with a small number of users and will potentially roll out to its 25 million streaming subscribers should the adjustments prove effective. With thousands of movies and television shows available for streaming, the proposed changes should help users when casually browsing for something to watch.
