I would recommend Panorama Tab Groups over Panorama View fyi just because panorama view doesn't see a lot of maintenance in recent months. They're still there, but in hibernation so they don't get new features right now.

full disclosure: I'm the maintainer for Panorama Tab Groups right now so I am slightly biased. I do think photodiode and the guys in charge of Panorama View are way better than I am at this, but since they're not active right now, I've created a fork so I can have a more up to date add-on

I endlessly miss tab grouping

Simple Tab Groups add-on (with latest updates) works wonders and I'd even say better than old Tab Groups.
