I'm not telling people to gather pitchforks against the new layout, but one place where it's shamelessly obvious they copied a part of the layout of steam where it is inferior to the previous system is the screenshots. So they pulled a "me too" just for the sake of "me too." There's nothing wrong with making your layout accessible, or even familiar, but if you are doing it just for the sake of "me too" that's kind of disappointing and I respectfully disagree with such a mindset GOG.
This will sound like a petty criticism, and I guess it is, but so too could I liken GOG's attempt to play "me too."
I absolutely abhor steam's system. At least this one doesn't have that stupid slider, the arrow will scroll the entire mini screenshot gallery, but yeah, I think most people are going to flip through all the screenshots quickly like I do.
Even if they don't, it's nice to have the option. What am I even talking about? In the old system you clicked one of the fixed screenshots that are featured on the front. Then you have an arrow which will scroll to the next screenshot. Why is this more convenient? The new system requires some new unnecessary steps if you're just looking to go to the next screenshot.
You must reposition the mouse to the next screenshot each time to a unique position, in addition to reloading the "slide" of mini screenshots in order to get a new slide by clicking the arrow. I know, again, it sounds petty, but then why was it changed?
I thought I'd just point this out. This is just one discrepancy, and I'm sure there are others I could point out. A UI expert could probably sit down with some people and look for ways to optimize the interface in this way. I can think of a dozen improvements alone I want to see with the library, and I'll perhaps share them in the future.
I agree on the screenshots. Most of the changes where... there. Nothing that got me excited in either positive or negative way. Took a few seconds to "learn" where the old stuff is now but the only "stand out" for me was that the screenshot section was far better previously.
