FiftyThree has made a number of changes to Paper, the digital sketchbook app, with version 3.0 now becoming a universal app that works on both iPhone and iPad, rather than just on iPad. The milestone release also includes a number of other changes focused on making it more helpful for productivity, with the app now allowing users to take photographs and capture notes quickly, with images able to be annotated and added to a virtual sketchbook "Space" dedicated to an idea or concept.
