When you hold the back button you can see all the apps that are running (suspended) and switch to one quick... but is there some way to get rid of one? (swiping up or down doesn't do it)
Why do I want to do that? For starters...
(1) If the app does things in the background (like Skype does), then you might want to quit it if you don't want it doing those things now (even if you normally like it it to do those things, so you don't want to block it in settings).
(2) If there's value in having an app resume rather than restart, then you may not want it to auto-quit due to other apps you run... so quit those others.
