I have a problem on my 4K 32-inch monitor - I can't get all my books to fit in any of of the "shelf" backgrounds so kindly supplied above. Even if I shrink the cover size down to 2x3 so that they fit on the first row, subsequent rows are still not sittng "on" the "shelves". This is not important, I've never even used cover view before, but now that I'm experimenting with it, it would be nice to complete the illusion.
