New to the forums. What is the best way to suggest app enhancements?

I'd really like to suggest the following, but not sure where to send.

1. The ability to "hide" movies from appearing in our your libraries (and a way to view/unhide them)
2. Separate the Movies tab under My Vudu into "My Movies" (which I own), and "My Shared Movies" (which I see as a result of sharing,) or something similar.
3. Allow us to sort movies by our own personal ratings.
4. Display our personal ratings (perhaps below the picture of the movie) so we don't need to select each movie to see them.
