It'll be nice if one could export a file to .doc, docx etc instead of using "Save As..." to those formats. The advantage is that you can continue editing your original document after you make the copy without the need to close the copy and reopen the original.
I hope this is a simple enhancement that may improve the experience of those sharing their word with user of other application eg MS Office.
Do not hesitate to reopen in case of mistriage.
