"Ugly, consciously for the hard code only"
It's a store front, providing access to a lot of content that wasn't previously available or isn't available elsewhere.
Seems insistent that I want Steam accessibility panels in my games (I don't), to social network, etc. No way to completely disable viewing of Windows titles. Lots of effort to get to play.
Though its to be applauded for trying a little to look like a Mac app (though not a lot: it's a square cornered window that resizes from any edge), it gets down marked for wanting to start every time your machine does (which it does by default), requiring near constant updates, assuming you want it to interfere when you're trying to play and constantly trying to sell you games you can't run.
