Under Notifications, add an option under "Show on Lock Screen" allowing users to reduce the information that appears on the lock screen. Right now, if my iPhone is locked and I receive an email, the sender's name appears on my lock screen, the email's subject appears, AND even a portion of the email's body appears. That can take up 6 rows! That is too many rows in my opinion, and also, there are definitely situations in which I prefer that the content of an incoming email does not show up on my lock screen. I respectfully suggest a new option like "Show Sender Name Only on Lock Screen".  With fewer rows used up by each notification, more notifications can fit on the lock screen.

Thank you!
