I've left in this file as an example of how to do it, but it's probably enough to just 'hide' free only code using if(flexible_faqs_fs()->can_use_premium_code()) { // free only code here } in the main code.

        echo $this->custom_plugin_data->main_menu_label;
        ?>, and use it on your website, please consider making a <a href="<?php 
        echo $donation_link;
        ?>" target="_blank">donation</a> to help fund continued development (and to keep Dexter in doggy biscuits!).</p>
