lockscreen notifications
You'll see that notifications are broken up into bubbles now and use 3D Touch to show hidden menu actions - just hard press on a calendar invite alert and you'll be able to accept or decline it.
3D Touch-enabled iOS 10 notifications work even better for Messages. You can immediately respond to messages as soon as you pick up your phone, without ever leaving the lockscreen. It's all done inline.
No more digging around the home screen and layers of app menus to check vital information. If you have a doorbell camera notification, you can see who's at the front door, use the intercom or unlock the door.
This "peeking at apps" capability via the lockscreen isn't limited to Apple's first-party
