GreenHopper is a great tool. It lets me plan the project with ease. Earlier the team was using Excel sheets and emails for sprint/release planning which is now recorded in GreenHopper with real time progress report.
The one question that I'm not able to find an answer is how do we plan accurately in future sprints? I mean with SCRUM, we get this sprint velocity. Is there a way to get this calculated automatically in GreenHopper. Any Gadget/Graph that can give me this value? Will this help in Effort Estimation?
