I've just started learning how to use Construct 2. As I wanted to refer to the manual while keeping Construct on screen, I turned the HTML manual into a PDF so I can read it on my iPad.
If anyone would like a copy of the PDFed manual, it's in my public Dropbox folder. The download link is below.
This PDF is created straight from the original HTML manual. It has bookmarks based on the manual's header structure for easier navigation.

EDIT: Please keep in mind that the HTML manual will likely be kept up-to-date. I'll only be updating the PDF when I know the HTML manual has changed and when I find the time.
