This comes very very late, but man, it's still great. The restriction that you couldn't play a game from your own library as long as it was shared was a ridiculous restriction, especially since it could easily be circumvented by going offline, so finally this nuisance is a thing of the past. I'm even more excited by the parental controls, though. They look really usable and properly thought through, which unfortunately is a rarity nowadays, where nothing gets implemented that has the potential to reduce engagement. It really looks like some actual parents had a say in this. Thank you!
