I genuinely believe many users would appreciate this:

A small yet extremely thoughtful idea for movie/tv lovers who use IMDB. When looking up a show and its cast, the number of episodes displayed under the actor is actually a spoiler! If you see a main character with less number of episodes than some of the other main characters, you know that character is most likely going to get killed off in the story. A simple toggle function to display   the number of episodes would be dank af. Nobody likes spoilers! Please consider this thank you!
