I want to talk about task management for a moment.

In my opinion, "closing" your apps like some people continue to do Android and now with the easier method on iOS, is mostly a learned behavior from computer usage than it is necessary for your device to keep running.
It, quite frankly, astounds me that so many people are so obsessed with closing out their apps. I simply have no idea why you'd want to manage your device in this manner. Both of the modern phone OS's are more than capable of managing memory themselves. I've been using iOS for five years now. I have never found it necessary to worry about what apps might be running. The periods of time where I have used Android for an extended length of time I feel the same way.
There are times I use the task manager. But those are only in cases where I think an app has locked up or if I want the app to start over again from the beginning (like a game or something). So I'm not saying it's completely worthless. But the obsession of some people about having to always make sure they "close" out apps on their devices is just truly baffling to me.
I shouldn't have to "manage" my phone. I should be able to pick it up and use it. This is one of the reasons I'm still on iOS. Whenever I use an Android device as a daily driver, I feel like the phone requires me to manage it. I, quite frankly, don't have time for that. That's why I'm a little disheartened at some of the changes Apple has made to iOS that seem to be more of a response to silence a very vocal minority than it is to enable the device to work better.

I particularly dislike the fact that you can't swipe away the tasks continuously, having to wait for the task preview to center itself before another swipe is allowed.
Just use three fingers to swipe up the three visible apps at a time. Now you're three times as efficient at managing your phone!
