Mail's VIP feature is great. I can "star" the people most important to me, thus enabling sound and Lock screen notifications solely for them. It's a great way to make sure I'm alerted when I get email that matters, and avoid being interrupted when it doesn't. My problem? VIP currently only exists as a feature in the Mail app. There's no way to do the same for Messages or any other communication app I have installed.
I'd love to see VIP moved from Mail's settings to Contacts proper, so that I can make sure the people who are literally "very important" get through more easily, no matter how they choose to communicate with me. And it'd be great if it happened with iOS 9.
