Good on Twitter for living up to their end of the bargain: the redesigned, uninspired iPad app has already been updated with Slide Over and Split View, which lets you keep your Twitter timeline next to other apps. (Be careful, as that may lead to decreased productivity.)
Kind of odd that Twitter isn’t supporting Universal Links for twitter.com links on iOS 9, though. It’d make perfect sense to be able to tap a link to a tweet and view it in the native app.
Also absent, but not surprising: Safari View Controller. But we already know why.
