I would like to propose if it is easily doable that when you type in the applications list a search filter should pop up, I find myself trying to hit the keyboard every time I am searching for an app, before realizing the list is not searchable. Every other list is on the phone so it seems inconsistent not to be able to search the list. I know there is the app search widget, but double tapping the menu button is far more convenient than long-tapping it (which doesn't work on the switcher), swiping to the right desktop and hitting the widget.
Thanks and sorry if this has already been discussed
