It makes use of the new Containers experiment to provide a similar tab organization mechanism as TabGroups, and presents them in a vertical sidebar which IMO makes for a much saner workflow for heavier tab users. The identity encapsulation that comes by default with Containers might not be what you're looking for in a pure tab management system though, but as Sea Containers shows, some variant of tab grouping can definitely be implemented in WebExtensions.
Though Containers are mutually separate in terms of the cookies etc. (they're more like the good old 'Profiles' that I still use for keeping my 'work', 'personal' and 'dev' work separate) this still looks interesting. Thanks.
