Connect is really excited about the new Split View on iPad. Here is an article from the Cult of Mac website discussion Split View:
Split View lets you read articles in Safari while composing an email in Mail, enjoy a novel in iBooks while taking notes in the Notes app, and talk to friends via iMessage while organizing your schedule in Calendar.
But is Split View as game-changing as it looks at first glance? You bet it is.
Activating Split View is as easy as swiping your finger in from the right side of the display. You’ll see Slide Over initially — another feature that’s new to iOS 9, which I’ll talk about in another piece — but if you select the second app you wish to use and then enlarge the window by dragging its left edge into the center of the screen, you’ll enter Split View mode.
You can now use both of the apps displayed on your screen simultaneously — as if they were one. There’s no need to keep double-tapping the home button to jump in and out of apps, and there’s no reloading, so you get a seamless experience between the two.
