I vaguely think I had the extension version at some point but it was probably in an awkward stage then.. I never really noticed the integrated version. From the way you describe it I think it sounds like a great start for at least some of the needs driving this. I suspect in many cases heavy multi-tab use comes from a need to lay out sets of documents for use together in some sort of spatial metaphor. The traditional desktop model often does a pretty good job of covering this for local files and native programs, but I find browsers to be far weaker at supporting it. As a complement, for the potentially-life-changing(-but-not-right-now-for-goodness-sake) things and other valuable resources I will almost certainly never find my way back to otherwise, I think it might be a nice start if I had a 1-keypress way to drop them, with metadata, into an local, indexed archive. The followup challenge to that would be a really good interface to getting stuff out again. Tools like Zotero could in principle cover the first part of this niche automatically already, but I wouldn't want the backlog archive (sluggishly) dropped together with my references without any shadow of compartmentalization, so I don't really view that as a ready solution.
