I would like to know this as well. Would be a very useful feature to rearrange complex diagrams. Now I need to manually add a new row, copy the contents and remove the old row

hi @Daniel Vera and @iGuido 

Sorry to hear about your frustrations with this diagramming tool. I checked with our product team and they confirm this is expected behavior, and not a bug. There is no drag-and-drop option available. The team is aware of this and it is on the product backlog.  As to when or whether this will be fixed, I have no answer, I’m afraid. 

The only workaround right now is a manual copy/paste. I hope this gives you some clarity. 

Cheers.
