The option to have Download button the document that doesn't have any fields (not via Actions >> Download but a simple download button).

I agree with Tom Maggio. At least once a week a client asks me to send them a PDF. This should be a glaringly obvious button at the top of the document. Make it flash, make it gaudy, make it OBVIOUS, just don't bury it in a menu! The recipient UX should be the easiest and most intuitive experience in the world to navigate. If I have to explain it to a kindergartener, it's too difficult.

THis is critical for me. As of now i have to coach my clients on how to download or print the pdf. My clients have board approvals and need to print pdf easily and quickly to compare to my competition.
