As to shortcutd developers, I can tell, that when Mugen 2400 mAh battery is in use, the lens cover is open all the time. shortcutd and quicklaunch could be useful still, if instead of monitoring the lens cover, it would monitor the camera shutter button. If camera application is already running, ignore it. But if camera application is not running, show the menu. For the shortcud guys, the lighter focus press of the camera shutter button could be usable, even if the camera application is running, IF camera application is not on the foreground.
