swipe right or left from app-launcher

Swipe right and swipe left allow to come back to multitask view in all cases except when app-launcher is displayed. Moreover when many applications are installed you have to scroll up and up to come back to multitasking view. This is also the same issue to view battery or network levels. Such feature will increase consistency of user interface. But such feature will need to find another way to implement shortcuts to favorite ambiences. I suggest pulley menu from lock screen to get access to a specific page containing favorite ambiences.
