Wish the change never happened. I don't see any benefits of the new view.
By making everything flat you've also made everything less distinctive. In the old view, the trending was clearly separated from new, there were very clear tabs for New, New this week, and so on. Now it's all muddled together, it's ugly. You could argue the old Nexus had a relatively dated style, but it was readable and easier on the eyes. The new one attempts to follow trends set out by other soulless corporate website design overhauls like Youtube. And it still is very restricted horizontally, which looks aesthetically worse now that there is no separation from the foreground and background. It's too flat, boring, and confusing.
There is also far less information presented, and yet it takes up monumentally more space. There's one fewer trending mods displayed, why? The New/Updated/Whatever table has 4 columns while the old had 5, and yet it has not become any more readable and I have to scroll more to see less. The thumbnails and font size has increased at the cost of information density and the benefit of... nothing. If a user wants a larger font, they can press Ctrl and +. I can't press Ctrl and - to bring the old density back.
What does "Trending" mean, is that the replacement for "Popular(30 days)" of the old layout? "Trending" carries less meaning, since I have to ask what it means. Make the tabs "Popular - all time" and "Popular - this month", don't make it worse because the word "trending" is fashionable.
The search results are okay (other than the inferior aesthetics, all flat etc.) and they mostly fit the page width. Why not do the same for the front page? I can understand the actual mod page since that can make descriptions look worse as they don't often have a lot of text, but when dealing with large (or rather very large in the new layout) thumbnails on the front page, there is no reason not to make it fit the page width.
I also wish the results defaulted to mods when I hit enter rather than displaying me a little fraction from each category in the pop-up search menu, and then doing the exact same thing but larger when I hit enter instead of the small "View all" button for the mods. Mods are the primary use of the site, if someone wants to look for users or collections, have them click the extra button instead of most people.
I don't understand why the Nexus people responsible for this consider the aesthetics changes an improvement, especially since usability is inferior. Are they deliberately trying making the service worse? Do they not use the website? I can only assume with the amount of people being displeased at this change, especially if they're serious mod creators, the likelihood of them moving to or straight up creating competing sites will be higher. Is the change supposed to appeal to the younger audience that grew up with phones (and therefore phone-centric website designs) rather than PCs? They can get bent, they're using the internet wrong. You don't install Skyrim mods on Android.
