Apple's rumored iPad mini 4 might support the Split View (two apps running side-by-side) feature revealed for the iPad in iOS 9. A resource file found within the Safari 9 browser in OS X El Capitan shows support for Split-View in Safari for the iPad mini. If true, this could also mean that the specifications of the upcoming iPad mini 4 will be on par with the iPad Air 2, which runs on the Apple A8X.
Developer Hamza Sood and 9to5Mac also report about a developer tool in El Capitan that's designed for developers to test the responsiveness of website designs allowing the simulation of an iPad mini with Safari in split-screen view.
Announced at WWDC in June earlier this year, the new version of Apple's mobile operating system -- iOS 9 - comes with Split View, a feature that brings multitasking capability by allowing users to run two apps side-by-side, with the ability to adjust their screen space.
The feature was not announced for all the iPad tablets. Due to hardware limitations, only the iPad Air 2 supports Split View. If the forthcoming iPad mini tablet is capable of supporting Split View, it is very likely that it comes with the same robust A8X SoC, or a comparable offering, as the iPad Air 2.
Launched in 2014, the iPad mini 3 was a minor improvement over the iPad mini 2. Apart from its availability in Gold, and the inclusion of Touch ID, last year's model didn't have any other new feature. The possibility of seeing a significant hardware boost in the purported iPad mini 4 doesn't seem too far-fetched.
