3. Logical Settings Locations
A general reorg of settings would be helpful. Some of the stuff, as my colleague, Contributing Editor Serdar Yegulalp notes, is quite buried.
One of my biggest complaints with iOS 5 was that it was really difficult to get to the settings switch to turn Bluetooth on and off. You had to go into Settings, get to General, Wireless and then Bluetooth before you could get to the switch. iOS6 changed that a bit, by bringing both Wi-Fi and Bluetooth settings up to the top of the Settings menu. However, you still have to dive in to each category to get to the switch and any other options, like pairing with a specific device.
I'd really like to see a complete tear down and rebuild here. The way Apple has all of its underpinnings and options set up and configured is also long in the tooth. I know I'm likely to not get what I want here, but it would be nice to see some work on organization and logical groupings. It isn't always clear what is and isn't stuffed into settings and what might be tweaked in the actual app.
