Great for workflow, can't wait to see this evolve! Rated 4 out of 5 stars

This add-on is quite promising and I have high hopes for it. I run my tabs on top in the title bar so it seems kind of awkward having it below on my setup. I think it'd be great if the group tabs were like pinned tabs, at the very beginning of your tab bar before the actual pinned tabs. I use another add-on called AppTabs Plus which lets you adjust the pinned tabs a bit, you can put a separator between those and your regular tabs. I think if this add-on was separated from your regular tabs in that sense, it would be very aesthetically pleasing. With that said, I'd definitely give it five stars if it was more seamless with the interface but overall functionality seems great so far. Nice work!
