Director filter on watchlist idea

My watchlist is very long (almost a thousand titles), so it can be hard to find what I need. I think it's great that I can filter by genre etc., but it would be wonderful if you could type in a certain director or actor you want to see a movie of. I can't remember all the movies by all the directors that I at some point thought would be interesting, so it would be great to be able to see them in a row easily.
