Change proposal

Hey, first of all thanks very much for your work. Excellent plug-in, my client loves it!

Please allow me to propose a small (non-breaking) addition to the plug-in logic. A requirement came up for me to always show a placeholder for certain products. For the sake of clean code, I thought the best way to do this would be to add a little filter at index.php:181:

if ( ! empty( $thumb_ids ) && ! apply_filters("woosq_always_placeholder", false) ) {

instead of just

if ( ! empty( $thumb_ids ) {

This gives us a way to alter the behavior in another plug-in or the theme functions.php:

add_filter( "woosq_always_placeholder", function(){ return true; }, 10);

… or, thanks to PHP 7.4 arrow functions:

add_filter( "woosq_always_placeholder", fn() => true ), 10);

I hope you will find this useful and consider including the code in future updates.

Thanks!
