Used the site for a good while happily discovering mods and applying them to games. This change has me feeling like I am fighting the website UI and searches to do what was very quick before, find new and updated mods, read brief descriptions, and then if interesting look closer. Missing the comments search as well, usually a good place to research conflicts between mods or things to tweak. Now there is more clicking and scrolling to get to or search for where I am wanting to go. Additionally the site theme changes to background and text are exhausting to look at over a period of time. There's less information on the game pages probably due to the increased space where everything is so far apart now. Also an odd to me priority on collections vs new and updated mods.
I've been able resolve most of this with the CSS mod changes to mod the modding web site, thanks to the community for this, helps to make reading site pages not exhausting so quickly.
If it was a good user experience change the change itself would be intuitive, have less clicking scrolling to get to where a user is wanting to go, feature parity, and we or at least probably myself at least wouldn't be here talking about it or thinking about the UI/UX in any way. I would much prefer to just be happily discovering mods and applying them to games.
