Been tackling many of the different courses at Proko and have found myself going back to the videos to refresh but sometimes I just want to access the PDF files to get a quick summary of the lessons in like the Figure Drawing Fundamentals and Anatomy of the Human Body. Is there a way to be able to download all the pdfs/materials in one packaged download? I think it'd be a nice option to have, going back to every lesson to get every pdf individually is a bit tedious. Being able to download all the videos could be useful too.
