Why isn’t Image Intense available in the Visual Builder?

We’d like to, but at the moment it does not exist due to limitations/restrictions Elegant Themes has in place for 3rd party developers. However, we actually prefer the backend experience for Image Intense due to the amount of features and customization that’s possible within the plugin. At some point, Elegant Themes may decide to make this a little easier for developers to implement custom modules, until then, Image Intense is fully functional from the back end editor.
