One of the features I'm most excited about in iOS 9 is split view. Split view doesn't restrict the second app to the side bar (that's what 'slide over' does). It basically lets you run both apps at the same time, letting you interact with both side-by-side. Very awesome.
With that in mind, was hoping to solicit feedback from everyone here. I'd like to put together a list of iOS 9 apps that support split view on the iPad. If you know of any, go ahead and list them below!
