Slight Bug Re- Custom Lists

If you are creating a custom list and attempt to add a movie that you don't have in your collection, Listal dumps you to a white screen. For example - my Movies list contains the last 100 or so movies I have seen (copied from my Netflix list), so I don't want to add Star Wars, since I saw it years ago, and want Movies to reflect what I have watched recently but if I am creating a favorite Sci-Fi movies list, Star Wars has to be there. 2 options would work for me. Allow adding movies that are not in my Movies list, or 2 allow me to change the added date, so I could move a recently added movie way back in the order it was "added" since I (and I'm sure other people) are using the Date Added field as the Date Seen.

Thank you very much for listening.
