I've started using Note Taker HD as my primary notetaking app. In conjunction with Goodreader, I've got my bases covered for annotating PDFs and taking notes etc. The only problem I have is how do you organize the notes? I want to be able to have a "notebook" for my Lab book, for my course notes and for maybe any "miscellaneous" notes I want to jot down. I know PenUltimate can do that but I don't want to buy a separate app just for that. Anyone know a way to do that? e.g notebook for bio, notebook for physics, notebook for chem, etc. etc.
