I'll just put this here: http://www.streak.com It's pretty awesome at this kind of email management stuff right inside gmail.
We gave settings to disable that when it launched, but that was obviously not sufficient especially since it was on by default. After it started to roll out and we got complaints pretty much instantly, we turned it off within a few hours.
So ya, if this soured you permanent off of Streak then obviously that sucks big time. We definitely learned our lesson though, so hopefully we get one mulligan.
