Two key points of feedback on the mod list/search results page:
1. As others have said, the tiles are too big and seem to scale to different sizes depending on the browser window dimensions. You should be able to fit more mods on desktop-based windows at once, even if the window size and aspect ratio isn't a standard monitor screen.
2. Scrolling is laggy in the new design, almost like it's trying to achieve smoother scrolling and failing.
