When using Confluence's macro browser to add a macro to a page, it is often faster to type a part of the macro's name into the search box in the top-right corner than to click through the categories on the left. When typing "PDF", all of the macros provided by your add-on are shown, except for the "Current Date and Time"-macro. The reason is that this macro doesn't contain the word "PDF" in its title or description. It would be very handy for users if they were able to see all of the PDF-macros when typing "PDF" in the search box, so please consider adding "PDF" to the "Current Date and Time"-macro's title or description. E. g. "Print the current date and time of the viewer respectively of the PDF export" in English and "Bettet die aktuelle Zeit auf der Seite ein. Sinnvoll um das Erstellungsdatum eines PDF-Exports im Export zu dokumentieren." in German (this probably applies to other languages, too).
Best regards and thank you for providing this great add-on for free.
