Welcome to the desktop
Pick an article from the sidebar and it opens as a window, maximized. Restore it from the title bar to drag, resize and snap it; open several and switch between them from the taskbar above. Images inside an article open as child windows; Escape pops one back down. The whole arrangement lives in the page URL, so it can be bookmarked and shared, and Back undoes the last thing you did.
This view is built with PUDL, the Pleasantly Usable Design Language. Every article is still a page of its own; the ↗ button in a window's title bar takes you there.
