Thanks, I've been waiting for this. It's still experimental (under "about:flags"). Stacked tabs are great, but unfortunately "tab grouping" is not that, it's just a feature that makes it possible to select several tabs at once?!

With real tab grouping in Chrome, including a feature to only load tabs when selected, I could finally make the switch from Firefox and the great "TabGroupsManager" addon.

Unfortunately, Chrome dev team decided that opening all tabs on startup is a good thing and marked intelligent lazy loading of tabs as "won't fix". I cannot find one good argument against this feature, unless it's extremely difficult technically (which is unlikely).
