It certainly adds insult to injury that the ACM Digital Library redesign from a couple years back has been a huge downgrade in usability across the board.
Yeah, it is quite annoying. A very typical flow is to find the papers that cite a given paper, and that is now hidden beyond a 3-click flow that involves an icon and a weird popover sidebar. Just show the citing papers as a list already, like it used to. It's clear that whoever designed the site doesn't actually use it. Don't get me started on all the completely unnecessary stuff that floats around in response to scrolling. Just stop with that crap already.
