I tried like 5 different tab grouping addons and this is the only one that actually does it properly. Albeit not exactly what I was looking for, but it works.

Great for managing your tabs! Love it

amazing that someone remade this feature into addon. love it.

It's preventing me from switching to Chrome

Better than the other panorama add-on because it can autosave :D

The only downsides I can think of is that you can't move multiple tabs to another group at once or search through tabs like the other panorama add-on :/

Please add option for custom CSS for Panorama page

Can't live without this! Replaces the old Tab Groups beautifully. There's only one thing that would make this even better: a way to show the Most Recent tabs opened across ALL groups. I work on a few tabs from a lot of groups and it'd be great to be able to see all ones I work on recently in one place without having to open each group separately.
