1) Under Notifications, add an option under "Show on Lock Screen" allowing us to limit the information that appears on the lock screen.  Right now, if my iPhone is locked and I receive an email, not only does the sender's name appear on my lock screen, the email's subject field appears too, and even a portion of the email's body appears.  That can take up 5 rows.  That is too many rows in my humble 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.

2) Likewise, at the Inbox view, add an option allowing us to limit the information that appears with each email.  I don't need to see the first two lines of the body of each email at the Inbox view.  I prefer to see only the sender's name and subject field.  Right now, each email at the Inbox view takes up 4 rows.  That is too many rows.  I'd prefer that each email take up only 2 rows, freeing up space on the screen so that I can see more emails at the Inbox view.
