I'm curious...
With this number of people, you're obviously not using the option to
Show people added from movie credits. They're initially being added as invisible records, then you're doing something to make the ones you're interested in visible. With 1,759 movies, there's likely in the order of 30,000 people in your database—many more if you're not restricting the number downloaded (e.g., actors from main page only).
So I'm wondering if you have any routine for making the people you're interested in visible and downloading their information. I understand this might be simply clicking on people in Movie view if and when you're interested in them. This will make the one selected visible, and switch you to People view where it would only take a few seconds (hopefully) to download their information. In other words, they could be added on an "as needed" basis. On the other hand, you might use some systematic approach, like adding the director and "starring" actors each time you add a movie.
I use the other approach of using the option to
Show people added from movie credits, and then regularly downloading information for all the people added since my last update. I'd like to eventually provide a description of both alternatives and their pros and cons in the Help Documentation. And you might convince me I should switch to your method. I find the people I'm really interested in tend to get lost in a sea of 33,000 people.
