I've tried the LITE version and I seen the demo on their website. The plugin is very good, congratulations. I hope it adds more features and, today, I recommend the purchase. I'd like to know the roadmap and suggest new features, for example, being able to customize the final screen, add a CTA (add a shortcode, a form...) at the end, show a summary, show/hide in the card back two buttons (correct and incorrect)...

Regards.
