Benjamin Mayo, 9to5Mac:
Here’s a funny one: iOS 15 lets you place multiple copies of the same app on Springboard. This means you can have the same app duplicated across your home screens, as many times as you want.
The result of this, taken to the extreme:

More from Benjamin:
One way to do this is with the App Library. With an app already placed on your home screens, go to the App Library, locate the same application and long-press to drag it. You can then place it onto a home screen and your existing icon will not be removed.
iOS 15 also enables drag-and-drop for apps in Spotlight search. So you can skip the App Library and directly search for your app, then drag it out of Spotlight and place it where you want it.
Not sure if this capability will survive through all the betas, make it to the official release, but I do like me a screen full of Twitters.
