NuttyNet

+1 I used to do this all the time. Since the update to the app on OSX, I cannot do this any longer. When I try to modify in Preview, I receive a message at the top indicating that the original file could not be modified and a copy has been created. I must say that the new version of the app is disappointing. Seems like they tried to create the same experience as on the smartphone, but it is inferior to the previous layout of the app.
