The recents tab in Android can be pretty handy at times. It allows you to see apps you have recently had open on your device. This allows you to have a somewhat seamless multitasking experience on Android. You can open an app, launch another, hit the recents button and go back to your previous app pretty quickly without having to venture back to the homescreen, then back to the app drawer, then re launch the app. The new app switcher in Android N brings some new features. Now when you double tap the recents button from the homescreen Android will launch your most recently used app. You can double tap again from within that app to launch the second most recently used app. If you were needing to multitask between a series of apps you could close all apps from within the menu, then launch those apps and use this feature to quickly and seamlessly move between them No more endlessly scrolling through a list of open apps, unless you just wanted to of course.
