Highlighting known titles/actors when signed-in

I really hope this gains some traction because it would change using the site for me (and perhaps many others) so much.

It would be really great if you could flag known titles and actors when you're logged-in so that when viewing, say, a voice actor with hundreds of roles, you could choose to highlight or place at the beginning all the ones you were familiar with.

In recent times, finding out what you know someone from has become a major drag for certain actors with a long list of credits, and I think this would be the perfect solution.

It would add to a person's profile size, the impact of which I couldn't guess at, but hopefully it wouldn't be unreasonable - certainly it would be a lot less than the size of reviews of any title which anyone is able to write!
