This has probably been brought up by others before, and I genuinely can't believe that I've only just thought of this, but why doesn't the iPad Air/Pro have pinned tabs, like in OS X? This seems like such a no brainer, especially with Apple highlighting iOS 9 as a beefier update for productivity on iPad. It would go to great use on a touch surface. I really hope they add this feature in 9.3 or iOS 10/X. What do you guys think?
