Hide coupon code?

Dear friend,

First, I want to thank you for creating a really great plugin. I wrote a post to share your plugin with everyone: https://wpcanban.com/wordpress/thu-thuat-wordpress/chen-ma-giam-gia-vao-wordpress.html

But the plugin still has a small shortcoming. Can you add function to hide coupon code (like https://demos.famethemes.com/coupon-wp/). Doing so will increase the effectiveness of affiliate marketing. I hope you do it.

Thanks so much!
