Along with a large number of great features in the operating system iPadOS, there is another useful feature, where you can open more than one window for the same application at the same time. This is a good thing for many situations like opening more of the map in the Maps app, or more from the window of the browser Safari (if you don’t want to use tabs).
Easy to open multiple windows of the same app on your iPad, here’s how to do it.
I know of
Open the application that you want to have more than not and keep it open. We’ll use the calendar app for example, so follow these steps.
1) with the open application on the screen, swipe up from the bottom to summon the app bar and the Dock.
2) Click on the icon of the application itself in the application bar and Dock.
3) in the next screen, click the plus sign in the top right.
4) this will open the app a new window. You can follow the same steps to open windows subsequent for the same application. Or use this procedure to switch fast between those windows, which you can do also in the screen to switch between apps or the App Switcher.
