I am currently working on creating a mucow so that I can have a custom widget for Muse. I noticed that whenever I use other peoples widgets they have an icon that appears when the widget is placed in Muse, which is pretty cool but I also think it makes the widget easier to see. I was wondering how I could apply my own icon to the widget I am creating? I am sure it must be an attribute in the <HTMLWidget> tag in the mucow but I am not sure.
Any help would be greatly appreciated!
