Combined sort by both "Most Recent" and "Recently Watched"

[jpsnyder]

It would be nice if there was a sorting option that combined the "Most Recent" and "Recently Watched" sorting categories, such that each TV show is ordered by the airdate of the next unwatched episode or the date of the last episode watched, whichever comes first.

This way the shows you are currently watching are at the top of the list, but when the first episode of a new season airs it pops up to the top of the list. If I choose to watch an episode it will stay up at the top, but if I don't it will slowly move down the list as I watch other shows.

I know we already have the "New Episodes Always First", which I do have on, but the problem with that is that if I don't watch the episode soon enough, it then falls off far down the list since it was recently watched awhile ago. And then I forget about it :( The time that new episodes are pinned to the top seems pretty arbitrary. This new combined sort method would make things more standard.
