Currently, in the library, you can filter games by tags — search for a tag, press on it, and it will only show games with that tag. What isn't present is the ability to exclude games based on tag. Although I can include games with an NSFW tag, I cannot exclude them.
I can see why this function didn't exist in the past — all games in the library were yours, so automatically, they probably didn't need to be excluded. But with the Family Sharing feature, the library is now filled with games that aren't ours. My one friend shares amazing indie games with me, but I really don't appreciate seeing his extensive Nekopara collection while searching for a game to play.
The function to exclude exists in the Store itself, actually. Why is it absent from Library filters?
