There is a lot of wasted space on the new pages feed. When viewed very zoomed in, it is fine (I guess), and makes use of each line on the left due to test that wraps around. When zoomed out however, it fails to remove this extra line of space, and simply makes each box bigger than it needs to be. The three images at https://en.wikipedia.org/wiki/Wikipedia:Page_Curation/Suggested_improvements#Fix_large_screen_New_Pages_Feed_display_to_save_space (where the problem is also reported at the suggestions page). The third one indicates how the feed could be modified to show more items per page. This would be helpful because it would make it easier to see repeated submissions from the same users, and allow scanning a larger number of pages at the same time.
