I'd like to add two extra widget containers to the Jewelry Box theme panel. I've attached an image to show where I'd like to add them. I was able to add them in 2.2, but now in 2.3 when I made the same modifications to the config.json nothing happens.
I've made a new layout called "layout3" and added that to the manifest.json. That shows up well. See attached image.
But when I edit the code to try add two more containers, nothing happens. I've attached a snip of my code - I'd be grateful for any help!
