Update to my previous post: Just downloaded the nightly build, where Panorama is looking much more polished. Hooray!
You can create tab groups from the Panorama view by dragging a thumbnail outside of its group box. As far as I can tell, you still can’t add new (previously un-opened) tabs to a group while remaining in the Panorama view.
It appears that the Windows 7 Aero Peek quirk whereby individual tabs are being treated as separate windows still remains. If anything, I would have expected each tab group to be treated as a separate window. I don’t know if this is a problem with Windows or with Firefox.
In the Panorama view, App tabs are now represented in every group as a favicons, which is a big improvement! The redundancy is a little bit strange - I think expected to instead have all the App tabs grouped in one place, separately from the other tab groups. But the current design does allow you, to decide whether you want to pull up a particular App tab within the context of one Tab group rather than the other.
The highlighting around the current/last tab open is now a blue-ish glow rather than a drop shadow, which is a bit less subtle than the drop shadow, but I’m still finding it difficult to pick out when scanning through a number of thumbnails.
Spotlight-like feature doesn’t appear to work for App tabs. Also, it would be really really awesome if it could search the text within the tabs in addition to the title.
