A new VIP feature in the Mail app makes sure you won't miss an important message from your boss or spouse or anyone else you deem worthy. Just star the person's name and you'll get notifications of incoming mail right on the lock screen. You'll also be able to look at all your VIP messages in a single folder.
Mail also now lets you add photos and videos right in the compose window, so you no longer have to go into your gallery first. That's nice, but we'd like to be able to attach documents from this window, too.
