There’s nothing quite like condensing your app collection into a single pane. That’s not always possible though, and so Apple is now allowing users to essentially hide pages of their home screen.
Long press your home screen to enter ‘edit mode’, and then tap the dots above the dock that show how many screens there are. From there, you can simply toggle pages on or off.
This also hides the apps on those pages, but that doesn’t mean it uninstalls them – it just adds them to the App Library – you can find them easy also with a spotlight search.
