Finally a worthy replacement to the Simple Tab Groups add-on.

I really like the minimalistic approach - no thumbnails and other not needed features, yet at the same time powerful with a lot of options to easily manage and automatically group your tabs.
The sidebar is also a really welcome addition which eases the navigation between tabs and eliminates the need for a separate addon.

Truly a great addon.

Thank you, searched for this!

After Quantum killed off Tab Groups I've been waiting for a similar extension to take its place. It doesn't have all the features that TG had to offer, but I recognize that it's the limitation of Quantum's current state rather than it not being a feature that the creator had forgone.

Overall it's great and I'm looking forward to future updates.
