Currently, apps on Android tablets open in full-screen by default. When the new mode is enabled, each app will appear in a window with controls that allow you to reposition, maximize, or close the app. You’ll also see a taskbar at the bottom of your screen with your running apps.
It sounds a lot like the iPad’s Stage Manager feature that similarly lets you resize and move windows around your screen or pretty much any desktop operating system. Samsung has also offered its DeX experience for years, bringing desktop-like windows management to Android apps on Galaxy phones and tablets.
