Looks amazing! I love the fact that it ties into tab hiding and I can add and rename groups. Instant 4-star for functionality and it was exactly what I was looking for.

I would bump this to 5 stars if it was a bit more visually appealing. Maybe options to color groups and tabs, or change the background of the Panorama View page to spice things up, but I know that functionally it's still being improved on so this really is not a major deal. I will continue to use this addon for the foreseeable future, and it's perfect to use at work.
