I was talking to my parents on FaceTime and wanted to look something up on the web in parallel. In the past, the iPad would bring up Safari and while I could still talk to them, the video was hidden and they could not see me either.
Today this happened:
Ah, right: I had just installed iOS 9, which brings split screen and picture in picture capabilities to the iPad.
It’s not like I missed this tremendously in the past, but it certainly is pretty cool and it’s easy to get used to it.
