We use Zube.io these days. Everything is just a GitHub ticket under the hood, it just slaps a PM friendly UI on them. I'm a fan.

Close, but not PT. PT doesn't have the concept of status columns. It is effectively in the active running iteration, or it is in the backlog. What fits in the running iteration, is based on velocity.

I love that it is just GH issues under the covers though, that's smart.
