The completely redesigned interface of iOS 7 meant a lot of users lost some familiar, and legitimately useful, navigational elements. Now, with Apple's recent iOS 7.1 update, you can at least get back one of them: button shapes.
In the menus on iOS, the default is for buttons to be text-only, with a " General > Accessibility and toggle on "Button Shapes."
Now, the text buttons within the Settings menu are surrounded by a larger shaded arrow shape. Other text buttons are also filled and surrounded by a darker colored rounded rectangle.
Personally, I don't like the look of the buttons option as much as the plain text scheme, but it certainly makes clickable buttons more apparent in the OS.
