I wrote a guest blog post over on the Aurora Bits site, about the user experience in SharePoint Modern lists and libraries…
By the way, while you’re on the Aurora Bits site, I recommend checking out their FlyView tool for SharePoint. It’s a very cool SharePoint navigation tool, giving you a dropdown/flyout navigation system, complete with previews, breadcrumb, and filtering. It’s available for all flavors of SharePoint 2010 and above, and there’s a free extension available for Chrome or Edge.
