PDF Download button & Boxzilla

Hi,

I really like how Paul Minor is using a PDF download button, and the URL shows he’s using Boxzilla.

I think it might be a bit sneaky to ask for sign when downloading the PDF but it’s an interesting option.

Do you guys know how to combine “download PDF” capabilities with Boxzilla?
