Ok,
That is underestandable.
So i looked into the code and the change is easy enough (modifing the view.php is enough), i managed to do that.
But changing it in Jevelin parent theme i guess is not the way to go. I rather should create a copy of the catalog / framework-customizations / extensions / shortcodes / shortcodes / blog-posts under jevelin-child and make my modification there?
Or rename the catalog also under child theme? Would that make automatically new shortcode ?
