i would like the ability to create a mockup right from a working document to share with a client. this "sketch mode" would put placeholder horizontal lines in the text frames, x’s in the image frames, and assign an architectural-drawing-inspired, hand-sketched stroke around all the frames. there could be a layer for notes and flexible arrows for labels and client-focused descriptions, and any actual text, images, or page furniture already placed could be hidden. the designer could export the pages in a large thumbnail-size presentation and then modify the document based on client comments without leaving the working document. this would be sooo helpful!
