Graphically present timeline of watched/collected episodes
I think it would be cool and useful if the progress bars in the watched/collected screens was filled by what episodes you've seen, so that if there's a 3 season show, and you've seen season two, the 33% of the bar filled would be in the middle of the progress bar. Gives a nice one-look view of whether you are missing any of the latest episodes.
