so i think the option to have a windowed board would be nice. i just feel that using a quarterboard in a row of full boards would not work well. and yes window boards would be cable of being covered in a curtain and blocking out light. and can be looked through but not boarded up. personally i would say its more of a add on to a board. so it would be frame-board-window/reinforced window(same as a reinforced windshield)-curtains.
