Thank you Rashida.
I think this would be an important addition for SP Page Builder.
Through a different post, I learned that I can use SPPB to create blog posts within Joomla Articles, which partly solves this issue.
However, as you know, this option does not work well when using full-width layouts.
In other words, pages that are created entirely through the SPPB editor, will not have a publish date, and this is an issue for SEO and ranking purposes.
I hope you can amend your builder so that a publish date can be incorporated into the pages.
Thank you,
Hector
