iOS 9 Split-Screen Multi Tasking
While on phone calls on the iPhone or iPad we are constantly multitasking, but when it comes to FaceTime Video or Google Hangouts calls this isn't a good option. It is possible to switch apps while on a FaceTime video call and keep the connection, but you cannot look at the person.
It would be great if we could use the large screen on the iPhone 6 Plus an iPad to put one app on the left and another on the right. This would let users video chat and look at a document while still seeing the other person.
Outside of productivity it would also allow users to watch a video and browse the web or chat with someone at the same time without juggling an iPad and an iPhone.
