Unfortunately I am not the developer ?? I hope this feature will be available in the next plugin update!
I am very happy to purchase the pro plugin version for you to support you and hope it will help you to keep doing this great plugin but I were wondering how I can remain the custom CSS codes that I made to the CSS file when I upgrade to the pro or when you have the new update? If possible, I hope you will have a file for me to put the custom css code please!
I hope to hear from you before I proceed with the purchase!
Thank you!
