5. Unified (and Improved) App Switcher/Control Center
New to iOS 11 is the combined App Switcher and Control Center for iPad. Instead of Control Center being mostly unused space, and the app switcher giving one or two apps center stage, the iOS 11 layout puts them both in a single place. This “Mission Control” styled area gives greater flexibility to changing apps and settings, even without an attached keyboard.
Similar to alt-tabbing on a Mac, the new app switcher shows your most recent “open” apps, allowing you to quickly dive from app to app or space to space, similar to switching from window to window on your Mac or PC, as well as gives you all the Control Center toggles in a single pane (no more swiping to change song or adjust a HomeKit device), making it the touch equivalent of a keyboard shortcut.
