What kind of features would you like to see in the next versions of iOS or OSX? Realistic ones only, please.

What kind of things would you like to see in OSX or iOS? Maybe someone from Apple will see this (doubt it). In any case, it's a good way to just put all of the "I wish" features in one thread.

I want more easily accessible settings in iOS. Like in the notification center. I want to be able to turn data off easily.
