The new PDF views in the iOS apps for Dropbox & Evernote both use PSPDFkit, which supports annotations & bookmarks, but that hasn't been implemented in either app. Support in that department would be huge to me as I'm a PDF reading, highlight loving, multi-device using front end web developer who often looks back on his references. I've used GoodReader to work with highlights and annotations, but it's UI & usability issues get in the way for me. Crossing my fingers that this is in the pipeline for both apps. Oh, and Evernote: please do what Dropbox is doing with the landscape view showing full width as that's the best way to read PDFs on an iPhone IMHO.
