Notification icons in the status bar. Please. NC sucks.
I can get a little moon in my status bar to tell me about Do Not Disturb, which I have either turned on manually or scheduled to turn on. But I can't get a little envelope to tell me I have an email or a little speech bubble to tell me I have a text.
Badges suck too. If my phone app has anything more than a "1" badge, there is no way for me to tell if it's missed calls or actual voicemails.
Aside from notifications, my biggest gripe is no toggles. I'd like to be able to toggle my wifi, bluetooth, etc, from the lock screen or at least from NC. Having to unlock and go in to settings has become a little stale.
These are issues that have existed since the dawn of iOS and I think they deserve a fresh look.
