I used to close my IPad apps by double tapping the button at the bottom of the screen. With IO7, how is this done?

You still double click the button, but instead of there being a small red button on the app for you to delete them, just slide the pages upwards, and the small screen and app at the bottom closes. Hope this helps

You still double tap the home button. Instead of tapping on the small x's, you simply swipe the image up to the top of the screen and they will close.

You still double tap, but then instead of holding down on the icon until it toggles, you take your finger and swipe the app window up towards the top of the screen. The app will disappear and close.
