FlixFamily is a new website that offers an alternative user interface to your Netflix account. While it's not as elegant as the Netflix UI, it includes features missing from the Netflix website, and the developer seems open to suggestions. Here's a shot of the movie browse page for TV shows:

Cool Lists include titles that are expiring soon, award winners, IMDB titles, and Rotten Tomatoes selections.
One of the more interesting features of FlixFamily is sub accounts, which lets you setup different profiles for family members. You can password protect accounts, and also prevent kid's accounts from seeing "R" or "unrated" movies. I manage my kids account because even if I limit their Netflix account to PG or G movies, they can still see some pretty racy movie boxes. With FlixFamily the kid's account will only see movies in categories you select.

FlixFamily is an ambitous effort, and shows the power of the Netflix API.

A Roku app is in the works and should be available soon.
FlixFamily offers a free one-month trial, but if you want to continue to use it the cost is $4.99 per year.
The developer is looking for feedback on the site, feature suggestions, and submissions for the "Cool Lists." You you can reach Scott at hacking@FlixFamily.com.
