I just today noticed that the page layout for stories/bios on Universe had changed. It now shows the progress bar as you scroll through the story on the left-hand side. It also shows the "cover" image and the title when you first open the page; these then disappear once you scroll down to the story itself. It may have changed within the past few days, but I've had a tab open with a story for about a week now meaning to read it. So it'd definitely pretty recent.
I also noticed that in certain bios/stories with 4 "related champions" listed at the bottom, the circles are cut off for some reason. Check the bottom of Kindred's bio for an example.
