I a little confused with your plugin and another similar plugin at WP.org:
1) Are that plugin is a free versions of yours or not?
2) Are both plugins manage the real physical file structure (images folders and URLs) or not?
3) What is the best way to assign many images to Elementor Galleries widgets - by folders or tags or....?
4) What frontend (for site readers) functionality your plugin gives?
5) Do you make a deep security audit to avoid backdoors or security holes for a easy hacking?
