No, unfortunately we're not looking to sell the script at the moment. We've been working on it for a few months and want to see where this site goes before we consider selling the engine.
You actually can search for a keyword and then filter the results by popularity (total hits) and recently watched (last clicks). We're working on a few more filters which should be ready soon (By Length, Most Favorited, Top Rated).
Thanks for the feedback.
