Use Widgets, App Library, and More
The biggest immediate changes to iOS 14, and to some degree iPadOS 14, are on the Home screen. App Library is a new way to sort and manage your apps. Additionally, the Today View widgets have been overhauled. Not only do they have a new look, they can also be embedded on any page of your Home screen! Finally, you can now view videos in a Picture in Picture window while you do other things in iOS as was already the case in iPadOS.
Clean Up Your Home Screen with App Library
In iOS 14 (but not iPadOS 14), the last page of your Home screen contains your App Library. The App Library stores all of your apps in automatically sorted folders. You can now also hide unwanted pages to streamline your Home screen.
