And in macOS these days, Apple wants programs to look and work like they do on the iPad: simply. As full-screen, autosaving worlds. You’re supposed to open them from a simple Home screen arrayed with app icons, and you’re supposed to switch among them by swiping with your fingers on a trackpad or mouse.
