Upon using Figma Sites, one of the first things I noticed was that you can’t nest pages inside other pages or folders to keep related content organized in the sidebar (like /projects, projects/project 01, projects/project 02, etc.). Dividers, which we got last year, definitely helped a bit—but having collapsible folders or nested pages, like with layers, or pages in Framer, would seriously help keep things organized – especially for URLs.
