It has been sometime, as a loyal customer, suggest for copy of diagram directly to Microsoft Office such as Word. I was suggested to install the office plugin, but for me, I am longing to have such a feature for long time!
Now it is available. I think it is quite essential and convenience. It is a one of the most high frequently used operation for me personally.
Best of all it support partially copy and paste a selected group of shapes or region of the diagram. Before you might have to either use addon or save as a local file and open it and then copy and paste!
