When I visit the mod page for a game, I am most interested in finding out about the newest mods for that game. With the old "classic" layout, the new releases were not right at the top of the page, the current "hot mods" were. However, they were all neatly presented in quite reasonably sized panel which still left plenty of room to see the first of the new mods right from the moment of landing on the page.
With the beta layout, first there is a banner for Nexus premuim (fair enough), the "trending mods" take up more space, then there are the "popular collections" (I will never need to see those.). Then there is another banner for premium and then, finally, there is the "more mods" section with the new mods highlighted.
In other words, I used to be able to visit Nexus, go to a game-specific page and at least see the first few of the items that I wanted to see (the newest mods) straight away. Now I have to scroll past a bunch of other stuff before what I want to see is visible.
This is not an improvement in my opinion. The site is less accessible to me.
Ideally, some way of customising which items are show, or in which order, would be great. Then I could put the "more mods" section at the top, and shift the other sections down. People who like a different order could have it.
