Generally speaking I've welcomed the advent of iOS 7. One of the things I was unsure about was the process around quitting multiple apps. That is until someone showed me the shortcut. Quitting apps in iOS 7 involves double tapping the Home button and getting to the multitasking screen. Flicking the app preview pane upwards will quit the app. Once it disappears, another pane pops into its place and you can repeat the process.
On the face of it, this is much more laborious and error prone than with iOS 6. Fear not however, there is a shortcut in iOS 7 to alleviate the burden of quitting apps quickly. With parallel fingers, you can swipe up on multiple preview panes to get rid of them at the same time. On the iPhone, you can do three at a time. Closing browser tabs on Safari also seemed like a pain on first glance but once you figure out that you can push a window away to the left, closing tabs is much easier. Although this must be done one at a time. Yet another shortcut I was glad to discover on those iOS forums.
On another note, I'm not sure how useful the preview pane actually is. The aim is to let you make a more informed decision as to which app to reopen or quit. The thing is, apps in iOS 7 look so much alike that I've reverted to looking at the app icon to differentiate them anyway.
