This is such an awesome add on. I used to be from the million tab crew. I still kind of am, but in an orderly fashion. It's also great to handle different workspaces, I work on several different projects, switch contexts a few times a day and it helps quite a bit with my workflow.

Since it just stores bookmarks, everything is kept up to date across devices, something that I also sometimes do, several times a day.

I just wished it could store pinned tabs as pinned. Other than that, maybe the UX could be improved but I don't really care. It's perfect for me.
