Can it be build ?

On unlocking open menu (not Hildon) in portrait

Swipe from left to right open prefered app

Swip from right to left open dashboard, again open last run app

Swipe back for dash board, again for menu, again for prefered app

Thats all. (I am not a coder... just a user so don't blaim me if I make this sound simple)

You can almost emulate by using just dashboard and app menu by holding protrait and touch interface.
