Thanks for your suggestion. Not sure if there would be much interest in that from other users. We’ll see in the replies.
To me, it feels a bit beyond the scope of a movie cataloging app. Also, all that info is readily available by tapping the IMDb logo in the app.
Adding more titles is not too important and would create more work for you. If you consider adding a title, however, I’d like to see film editor. The editor is often the person mentioned in addition to the ones you have now, and editor interviews are often included in extras on a disc. As I say, not high priority…
