When we open the movie/series menu, above the play and background buttons we have access to other movies (in alphabetical order or if you open a movie menu from a recently added movies you get the other recently added ones suggestion).
It would be nice if we can choose other options or even have more things in these menus, like a clever suggestion if a movie is from a collection, suggest the other movies from this collection rather the alphabetical movies suggestion.
If a movie is from a action genre, suggest action genre movies instead the alphabetical one.
The list goes further regarding more intelligent suggestions.
Same thing for tv shows that do not have this at all.
