Anyone try the new Steam beta? Just look at this crime against humanity:
In all seriousness, it's a beta, and overall, I like the new look, although it is too large. (And the above image is pixellated because Retina isn't working properly on the macOS version. Edit: nevermind, looks like it's working now. I don't think it updates properly when moving the window from a non-retina external.)
Still, I would not entirely be surprised if they just left it like that in the 1.0 release given they never bothered to fix the Snow Leopard stoplight icons. So, go give feedback!
I still wish they'd build native versions instead of using a cross-platform UI framework. We'll never get platform-specific features like the macOS emoji picker. Scrolling, although it *looks* native now, still isn't--the bar doesn't auto expand and there is no rubber band effect.
