It looks like what Opera was doing over a decade ago. IE8 also introduced coloured tabs based on tabs opened by others.
Firefox tried something similar to collections for those "tab collectors" with their Panorama (which is not available anymore these days), which was basically a visual 2d layout of tabs within groups. That's what got me the popup "are you sure you want to close 200 tabs" whenever I accidentally hit the close button.
All earlier attempts by non-Opera browsers seem to have failed so I wonder how long it'll take before Google takes this feature away. They're not a company that keeps new products or ideas around for long if they don't take off. I wouldn't get too used to having it.
