Apple’s latest beta’s for MacOS 12.3 and iOS 15.4 allow developers to test drive the new features and provide feedback. This new OS feature allows you to use one keyboard and mouse/trackpad to move to the edge of your screen and instantly jump to control, input, or even drag and drop content back and forth between devices. This would allow you to have an iMac, MacBook, and iPad and move your cursor between all three.
This will allow for greater productivity since you can use multiple devices for an expanded desktop to browse, test, or be creative just by moving edge to edge to work with each device.
