OK, thanks.
I’ve found the list of hooks for 2.x at https://support.bnecreative.com/product-support/wordpress-plugins/bne-testimonials-pro/ but am unsure which of the older hooks I can safely depend on. Some are marked legacy in the code so that makes me cautious to use them (and also am unsure if they are even used in the newer shortcodes). I couldn’t find a comprehensive, up-to-date list.
I have found in the code (in addition to the 2.x, cmb2 and puc stuff):
bne_testimonials_content
bne_testimonials_cpt_args
bne_testimonials_details
bne_testimonials_featured_image
bne_testimonials_list_above
bne_testimonials_list_below
bne_testimonials_list_single_above
bne_testimonials_list_single_below
bne_testimonials_masonry_above
bne_testimonials_masonry_below
bne_testimonials_masonry_single_above
bne_testimonials_masonry_single_below
bne_testimonials_single_structure
bne_testimonials_slider_above
bne_testimonials_slider_below
bne_testimonials_slider_single_above
bne_testimonials_slider_single_below
bne_testimonials_the_content
bne_testimonials_title
bne_testimonials_wp_from_email
It would be most helpful if the 2.x list was expanded to include both new and prior shortcodes that will be maintained going forward.
BTW – I have used other testimonial plugins in the past and tested about a dozen this time. I like yours because it is cleanly implemented, has all the features I need without fluff and produces attractive output. Well done! Also, FWIW, I avoid commercial plugins for a lot of reasons but your pricing for a quality plugin and developer friendly license makes this an easy purchase. It also makes me interested in your other stuff…
