JamesSkemp fork changes:

- Add Chrome URLs to setting pages.

note that if you are in Chrome, Chrome will not download the pdfs for you by default, to fix this
Settings (chrome://settings) --> Advanced --> Privacy and security --> Content settings --> PDF documents --> Download PDF files instead of automatically opening them in Chrome --> Turn ON
	chrome://settings/content/pdfDocuments
Settings (chrome://settings) --> Advanced --> Downloads --> Ask where to save each file before downloading --> Turn OFF
