Movies have been give a "recently added" and you can manually choose favorites.
Additionally, Home Sharing makes it easy for users to sync an iTunes library between up to 5 computers in a house. All authorized computers can share music, movies and TV shows between them, and will be viewed as part of a shared group where users can drag and drop content from one library to another.
The next feature is iTunes LP. All the artist pages have been given more visual material as well photos, liner notes and essays. iTunes Extra allows users to check extra content on DVDs and Blu-rays.
Finally is the App Management page which allows users to virtually arrange all the apps, while seeing a preview of how your iPhone home screen will look. You can also easily search for your applications, good for those that have tens or even hundreds of apps.
"iTunes 9 is a great iTunes release, with innovative features that make using iTunes better than ever and iTunes content richer than ever," added Steve Jobs. "iTunes LP, for example, lets artists share more of their creativity with fans and gives music lovers the feeling of being immersed in an entire album with art, lyrics, liner notes, photos and videos."
