More Customization Options in iOS 10
Ideally this would allow users to change the theme of the iPhone 7 while using iOS 10. Rather than a full on change of app icons and every small detail, we would enjoy simply changing the overall color theme of the iPhone 7 to match the current background or lock screen wallpaper.
Apple announced iOS 10 at WWDC 2016 in June, but did not mention any customization options for themes. The comapny did announce that they are opening up Siri to other apps, which is a step in the right direction.
