It would be great to have a PDF reader so we can upload PDF course material to go along with lesson videos, or just as a stand alone lesson.

Teachable has had this from DAY 1. If you upload a PDF, it is viable right there within the lesson.

In GHL, a PDF is download only... Students need to be able to read the PDF diagrams or have access to it while going through the course, without having to open a download.

Thanks.
