For a while now you’ve been able to pin websites to the home screen of your Android device. In the “next few weeks,” Google plans to let you pin certain sites to your app drawer, like you would with a normal app. However, this won’t work with all apps as they need to qualify as Progressive Web Apps for this. Once this takes into effect, though, these sites will be given access to Android’s notification settings, too. It’s coming first to the beta version of the app so you might have to wait a bit for it to come to your device—if you aren’t on beta.
