How it should be Rated 5 out of 5 stars

THIS is what they should have done from the start. Nice and simple.

On thing I'd like to know: The panorama button menu and the menu bar menu seem to work differently. The panorama button one has additional markups to indicate active tabgroup and inactive tabs. Is this not possible in the menu bar?

What I'd like to have, would be an option to give names to tab groups created by moving a tab to a new tab group right away, since that is the way I create most of my tab groups and unnamed tab groubs are terrible to handle.
Maybe one could also add an option to replace the tab group entry in the tab dropdown menu with your group menu as well, to save additional space.

This review is for a previous version of the add-on (0.9.1-signed).
