Query#:- We noticed that drag and drop has been removed from the roadmap.
We have checked your problem and we have implemented the Drag and Drop Feature for RoadMap in Volume 1 Service pack1 release itself. Due to some internal problem, these roadmap website has not been refreshed yet.
Drag and drop feature will be included in Volume 2 Service pack 1 release and we will resolve the internal problem and refresh the website asap.
