I've just installed your plugin which seems to be very cool.
Just a couple of questions if I can:
1) Of course I want all my downloads to be no-indexed by search engines. How do I select this option?
2) Is it possible by any chance to have a download link to work only when someone clicks on it and not when someone types the download URL in the browser?
I'm more concerned about question 1, so please let me know what I can do about it!
