Wipe your library
Are you embarrassed that you’re playing the newest iteration of Barbie Dreamhouse Party and don’t want your friends to see? Due to a new feature in Steam’s latest beta build, you can hide individual games off of your software list. According to Steam, “games that are hidden will not show up in library filters except for a new filter called hidden” — which will only appear on your client.
Well, it’s nice to have options I guess.
