I'm not going to try to muddy all the PDF processing with trying to figure out if the PDF contains ChordPro content and trying to render it in a different fashion (that would be a complete mess with how PDF libraries work). However, I'm not opposed to having an option to convert a PDF to ChordPro if MobileSheets detects that the PDF has text in it, and the text seems to be ChordPro content. If you want that as an option, let me know. Seems like that's not necessary if there are standalone files you can download instead of the PDF though. I don't believe it's very common to use PDFs with ChordPro content in them versus just using a .cho file. That's why this request has never come up before.
