Steam Update: In-game overlay, notifications, and a fresh coat of paint
Steam just released a massive update that reworks and improves most of the UI! It'll definitely take some time to get accustomed to this after being with the old Steam for so long, but it looks great.
I missed this being announced, and when I cracked open Steam last night on my PC it was quite the welcome surprise! The old UI looked pretty rough when compared to the rest of KDE. Now it feels like it fits in. I love it!
