Ability To Track Watched Shows/Movies

IMDb should generate lists for: 'Plan To Watch', 'Watching', 'Completed', and 'Dropped'. As well as each show/movie added to one of these lists the ability to track what episode you're on. For example say you are watching the Archer series and are on Season 4 Episode 6. You can add the show to your 'Watching' list, and adjust the episode to 6/13.

It would just be really helpful for people trying to organize all the shows they watch on multiple platforms, an organizational tool for media lovers, and also a tool that would attract more users to the site to utilize it - which they would be encouraged to contribute to other areas of the site as well.

You already have given users the ability to create their own lists in addition to the default 'Watchlist', so really if you wanted to simplify it the most; You could just add the ability to track what episode you're on.
