Very promising - looks to have a bright future. Was comparing this against the Conex add-on (a container-based solution), and quickly discovered that the two solutions do NOT co-exist nicely. This is not a fault of either tool, of course - they are both competing to do some of the same things. That said, my immediate thought that it would be awesome if these two tools DID co-operate: Conex for managing tabs between contains, and Panorama View to manage tabs WITHIN a container. Best of both worlds! Probably unlikely/impractical, but just thought I would throw it out there.

That aside, this looks to be the best non-container based TabGroups replacement out there. Keep up the great work!
