Hi wohzi.
Thanks so much for the detailed description and nice Photoshop job.
Now I completely understand what you mean.
Sorry, more icons on the thumbs is not an option.
I pay a lot of attention to keeping the skin clean and not bloated.
Also, this will confuse a lot of users.
For tv shows, numbers on the thumbs show unwatched episodes. If they suddenly show ratings in the movie library and unwatched episodes for tv shows, it won't make much sense. It's not very consistent.
For List View, List Info View and List Info 2 View, ratings are displayed for all items in the list. Much like you're after.
You can even sort by user rating.
