That’s exactly what I was looking for.
And in order to get the same layout (date + meta over the title) in default Generatepress blog layout and in single post view, is there another function you can share here, or do I need to copy and edit the template files in my child theme?
I had to modify the function a litte (I used ‘generate_before_entry_title’ instead of ‘generate_before_content’) in order to show the date over the title but keeping the featured image on top. But this function has move the date only, and I need to move the tags as well, now tags are still under the post content and I’m unable to figure out how to change that.
