@wkrp28 I have in the past requested that "Enhancement" also.
For shows like Doctor Who which is into its 30+ season, it's a real pain to scroll past all of the seasons.
Another thing that changed a few months ago was the art. If you have different art for each episode (as is the case with Docror Who) it used to show the art correctly. as of a few months ago, it will only show 1 (randomly chosen) art for the entire series. It's not a big issue, just annoying when a feature like this is taken away.
So three things please Apple:
1. correct the sorting of TV Shows problem i.e. return to they way it was done in v10.5.3
2. revert back to showing art for each episode
3. add a "season" layer between the TV Show and the episodes
