Can you advise on how to edit the pdf layout? Or is thing being planned fro the future, similar to how you have it for Event Booking (invoices).
Update: Ignore my question. I found where it exists (System/Messages).
I am seeing this Strict Standards message in the all the edit messages though:
Strict Standards: Non-static method EshopHtmlHelper::_getCustomFieldsTags() should not be called statically in .../components/com_eshop/helpers/html.php on line 207
