Attention gamers: The Steam client is now in beta for the new user interface. You can choose to use the beta client by going to settings and choosing UI Update under the Beta Participation section. You will be asked to restart Steam as the update is applied.
So far the new UI is looking nice and remains easy to navigate. The many new features allow you to better track your game progress, and see what games you play the most. The updated UI also has conveniences to help you stay on top of your favorite games by displaying a Recent News feed below your games. (Previously seen by right click -> View Update News)
The new interface includes both small and large improvements across the board, and is definitely worth checking out. (Don’t forget to send feedback by hitting the Beta sticker in the corner!)
Check out additional screenshots of the new UI below!
