That actually look pretty neat - I've wanted for a while now for my browser to be more "research" oriented, with ways of grouping all those related tabs that are all trying to answer the same question, or represent the same line of inquery.
It may help improve some tasks, but not exactly core product stuff.
If my capital were on the line, I’d be pretty annoyed seeing it spent that way.
I think you'll find you get a lot of mileage out of taking those particular glasses off from time to time.
