I really like this tool. It supports us in many ways. Getting an overview, prioritising, managing epics and stories. And due to the professional support it make a almost perfect tool. I'm looking forward to the next release.
This plugin is great and with each of the releases we've seen very positive results. We have been using it for a while now and have nothing but great things to say about the support / feedback received from the folks behind it and how it works in conjunction with GreenHopper.
Really Enjoyed using Dependency mapping.
This is an area that's important for teams to understand while working with multiple ART.
