iOS 7 Concept Features Widgets, New Lock Screen, Mission Control and More
Designer F. Bianco has posted a set of images to Flickr with some interesting thoughts on what useful changes Apple could make to iOS 7 to improve the user experience. Apple's user interfaces will likely face new scrutiny now that Facebook has laid out a new vision for how phone users interact with their devices with Facebook Home.
One of the more interesting concepts that Bianco shows is a 'widget' mode for apps that allows users to see quick information or change app settings straight from the home screen, as well as a quickly accessible settings screen that can slide out from the side to quickly adjust settings.
Turning Bluetooth on and off, for example, takes four distinct steps and the process could be much improved with a quickly accessible preferences screen.
