Just a thought as I’m looking at my top shelf with a few logos half chopped. Could the 4:3 images be edited to appear like 2x3 and 16x9 posters appear in the guide - with a couple of blurred banners on each side?
Think it would still look pretty clean if not cleaner and allow people to get the full art, rather than having some chopped off top and bottom, especially if it’s text.
