Now on Tap is also getting a Discover button that will show a visual feed of content related to what you're looking at -- say, articles on Jupiter. And if you use the feature's camera-based image searching, you'll be glad to hear that it now recognizes barcodes and QR codes. You just have to fire up the camera to find out whether or not that book or movie is worth buying. All told, Now on Tap is getting bread-and-butter features that you might just use on a frequent basis.
