Selection of genres based on "not-hide" and "not-empty"

[Nocta]

Hi,
I'm playing a bit with the possibility to sort out the games by genres and I really love it but I was wondering if it's maybe possible to ameliorate it a bit by:
- disabling all the genres you choose to hide in the list
- disabling all the genres where you don't have any game.

Thanks a lot and keep the good work.
