Similar to the way the iPhone camera overlays corners around a QR code that appears in a preview. When you point an iPhone camera at something that has a QR code, corners appear around the code and the camera offers you the option of visiting the indicated http link, for example. I'd like to overlay such an indicator on your plug in preview, not to visit a link, but just for visual aesthetics.
