It was definitely good idea. I implemented features which can help in many situations. Now you can stack widgets on the same place and trigger them all with one touch. I used it in Star Wars : Dark forces. Game is controlled with joystick and mouse, left/right on joystick does turn to left/right, but there is none setup which allows to change turning to strafing. You must press another button and then you strafe. So I placed that button and joystick over self and now it works fine.
