Valve released a Steam Beta update to bring in some tweaks to the shopping cart, and finally allowing you to properly set certain games as private so no one can snoop on your gaming habits.
For the shopping cart there's these new features:
- Inline gifting - just in time for the holidays, you can now purchase gifts for multiple friends (and yourself) without having to make multiple purchases. Plus gift messaging has been simplified to speed up the checkout process.
- One cart across all devices - items in your shopping cart will now follow you across all devices where you're signed in to Steam. Note that during the beta, the cart will only be accessible within the beta client.
- Private purchasing - keeping your games private starts before you even make a purchase, so the new cart lets you mark a game as private before you check out.
The private feature isn't just for when purchasing though. You can also, once updated, set individual games as private so they will disappear for everyone else. That includes hiding your ownership, in-game status, playtime, and activity in that game. At last, you can finally enjoy all your naughty games in total peace.
All you have to do is right click -> manage -> mark as private in your Steam Library. Either in the games list, or on the bigger box-art pictures in the main part of your library.
You can do the same on Steam Deck if you're in the beta. Just go into the properties -> manage -> mark as private on any game in your library anywhere:
