Hello
Thank you for using iceScrum 🙂 and thank you for giving us your feedback on this post (and the other one).
In an Agile / Scrum context, at the end of a sprint, what is important? Points. If something isn’t finished it should not remains in a done sprint. We also can’t copy stories to let them in the sprint because you will have 2 identical stories in your projects.
What you want is some kind of “ghost” of the story. In order to don’t forget what you have done but, again in an Agile context, is it really matter? For us, the most important thing is to make it done and get more points for the velocity.
So I don’t think we will go into this at least not like you suggest (copy).
