Hotlines and emergency numbers
For people in unfortunate circumstances it would be good to have helpline shortcuts (based off your localization). This could include a modifiable shortcut to emergency services that can be quickly accessed, a list of numbers for domestic violence and abuse, suicide hotlines, hospitals, your doctors, an a emergency contact number.
Emergency contacts and emergency services (911) should show a shortcut on the lockscreen for quick dialing, perhaps with a confirmation dialog to ensure that they aren't butt dialed.
