Would love to see the ability to save a reference directly from the reading pane.
Currently, the complete reference citation pops up if I click the citation, but I have to go to the search screen to add it to my library. It would limit interruptions to my reading if I could just mark that citation as one I would like to come back to and review.
Great product, but limited functionality of desktop app / offline, especially on touchscreen (e.g. MS surface).
