I don't think you can call removing basic features and making your site harder to navigate an upgrade. I've been lurking mostly in the past few weeks, real life getting in the way of any sort of drawing, and seeing people freak out about Eclipse being made mandatory. I initially put it down to people hating change, but having now been made to use it, and it's utterly terrible. How things like being able to view all your notifications on one page without having to go into multiple other pages made it through initial design boggles my mind, let alone how bad the navigation has become. The only explanation I can think of is that they want more "page views" to try and sell advertising, and so force you to load multiple pages to do what was previously all on one page. Not to mention that now every "preview" takes up about a quarter of my desktop screen, making me question if the people who designed this only used phones to view the site.
I get that change happens, and is necessary, but none of this appears to have been done to improve the site in any way, and I can't believe this redesign was intentionally done with the belief it was a better one. I had to search just to find out how to post this.
Edit: Christ, looking at this after posting it, there's so much wasted space, I had to scroll down just to get past the header. This is awful web design.
