Fit every library, collection and SmartScope on one screen shrank the rows with no lower bound, so a Kobo Libra with 45 shelves drew titles on top of each other. Keep rows at a readable minimum and run the shelves over further pages, repeating a section heading where it continues. Wide screens keep their two columns and turn the page once both are full, and only the shelves on the current page fetch thumbnails.
