Hello, I was thinking about taking my university notes with Penultimate instead of the traditional notebook. I would also like to download PowerPoint slides and PDF files from my professors and annotate them while in class. Is this possible with Penultimate? I saw someone using Noteability, which seemed perfect, except it didn't have easy integration with Evernote. This is why I am curious about Penultimate's functionality. In addition, once I upload the annotated notes to Evernote, could I keep going back to them to annotate them? Thanks.
