Sorting in our apps is the order a list of items appears from top to bottom.
I’m thinking you should want to look into Folders, and not from statistics, but from your main screen.
So go to your list of movies where you see all of them
tap the FOLDER button top left
then tap ACTORS and you should see all movies grouped by actor. You can sort by “amount” or A-Z. You can also search there, in the new searchbox above the list of folders.
Or,
Tap the folder button
Tap “Seen it”
Now you can see all movies you have Seen it: YES, or Seen it: NO.
As for fandango, I have that on a request list here indeed. For now I recommend just tapping the movie, tap edit, then add the format Fandango to it.
