Ios7 closing all open apps

[gSCVreg]

After double tapping the home button I have to swipe up on the preview page , no more jiggling icons each requiring a tap to close .
In ios7 can you close all open apps. at the same time ?

You really don't need to do that and it can cause the system to work harder than it has to. The system will free up memory when needed. Closing apps mean that those apps have to launch "from scratch" the next time you use them, whereas it takes less system resources to use apps that are not manually closed.
