This is an excellent point and I should have made it in my iPad post last week. iOS 9 was the first time Apple gave features to the iPad that didn’t also go to iPhone. When they made this announcement, I assumed it was only a jumping off point but now it’s been over 18 months with no new iPad power tools. I’m crossing my fingers for better iPad tools at WWDC 2017 in June.
