PDF app to annotate/hide all annotations
I'm looking for an iPad app to allow me to annotate PDFs, basically just highlight a section of text, and then to be able to quickly hide all annotations.
What i'm doing is reading PDFs with multiple choice questions at the end, I wanted to highlight the correct answers and then toogle the highlighting on/off while i'm studying.
I have Goodreader but haven't figured out how to do this. I'm open to buying a new app as I frequently study these PDFs for work.
