Would be nice if you could add region coding per season of a TV show, like you've now done subtitles and audio per season of a TV show.
A good example is, LOST: The Complete Collection where all seasons are region free except season 4.

Second suggestion is for the packing. What if you could specify what blu-ray case is it? Like a UK Amaray, Viva Elite, Eco-case, Criterion, etc.
We already have a very good thread on here about all the cases you can buy:
