Structure is a powerful add-on that lets you create pages, generate navigation, manage content through a simple interface and build robust sites faster than ever.
It forgoes the current template_group/template setup and creates “static” and “listing” pages that are all editable through a tree sitemap view. Now, traditional page style content and multiple entry pages can live within the same area. Your clients & authors will rejoice
