Good but...
I'm over 60, I'm not a revolutionary, but this mania of displaying headers and footers to print them in the document seems terribly old school to me! Plus it's stupid because URLs are always truncated and it often disfigures pages. Could anyone think of integrating this information, certainly useful, IN THE METADATA? Almost no one prints on paper anymore, and even if it would be easy for him to retrieve the metadata to print it. If you do that, it will become an excellent extension and I will give it 5 stars.
