I make websites for my customers and they want to be able to edit their text and images. With Oxygen, this would be a problem for most of my clients. Sure, they can use WP Bakery. But that delimits the functionality of Oxygen.
So what I would like to see added to Oxygen is a Customer mode where they can live edit their content in a fool proof environment. Also I would like the license key to be encrypted when entered in the license field. I don't want anyone walking away with my license.
