Apperance of links in Print PDF

In a recent update, the style on links in the Print PDF was removed (see #1437 #359).

While I understand that links don’t work in the Print PDF, there can be a need to signify that a link is present to someone using the print copy. For example, we’ve started adding a list of links to the back matter of each book that print users can reference if they want/need to look up a link. But if there is no visual indication of a link in the text, they won’t know there is information they are missing.

So my question is, is there a better way to share links with people using the print copy of a textbook? And if not, can we make it so the style of links in the Print PDF can be turned on and off in PDF Theme options? I am happy to submit a feature request if this is possible.

Thanks for the input!
