The only thing I discovered that I hope will follow up in a future release is the ability to to add more than one class to the image without having to do this to the plugin settings, like: class1 class2
Right now I cannot add two classes to an image from the content editor (eg: JCE editor) unless these two classes are added to the plugin settings for the class option as well. Adding just class2 in the plugin settings won't work if I add another class from my content editor. It would be great if whatever class is set in the plugin can append to any other class I apply to the image (like align-left, align-right, etc).
Overall, it's still a great plugin.
Thanks for your comments. We will see if it's possible to add this functionality.
