How to Use Slide Over Multitasking on iPad with iOS 10
iOS for iPad has dramatically improved multitasking with Spit View dual-pane apps and its counterpart, Slide Over. The Slide Over feature lets you quickly reference, use, and access secondary apps on the iPad without having to enter into full fledged split screen app mode, and without having to switch apps. This feature is great for quickly replying to an email, message, checking Twitter, making a note, or doing quick tasks in another app where you don’t want to lose the primary app focus on an iPad.
