We just deployed another simple, but important update to the Adafruit Learning System.  Downloadable guide PDFs now have links auto-generated and displayed, after the actual link using the adafru.it API. See the image above for an example.  We are constantly tweaking these auto-generated PDF downloads to make them easier to use, and bug free.  Let us know what you think.  Go to http://learn.adafruit.com, click on any guide, then click on the ‘Download PDF’ link in the left column.
