Google Chrome has been able to save sites as app shortcuts for years, but the built-in Apps page hasn’t been updated or improved in years. That might change soon.
The ‘Apps’ menu in Chrome, accessible from the Bookmarks Bar (if you haven’t turned off the button) or from chrome://apps, was originally created for organizing web apps and apps from the Chrome Web Store. Google started phasing out Chrome Web Store apps in 2020, and web app shortcuts are now more commonly opened from the system’s app list — the Start Menu on Windows, the Dock/Launchpad on macOS, and so on. As a result, the Apps page hasn’t been updated in years and has an outdated design.
