For someone who runs into this issue quite often; this is a great add-on. You'd be surprised how many issues and embarrassing emails have arisen due to Gmail incorrectly threading emails. Great job Streak :)
p.s.
Is it just me, but I can't fathom why the Gmail team doesn't scoop these guys up ASAP :)
Yes, it's so obvious it's hard to see why Google hasn't implemented it already. I wonder what will happen with this project, unlikely that Google would acquire something rather than assign a small team to fix this within a week?
