When writing for publication, it would be especially helpful to be able to edit in Verso-Recto format. According to the Chicago Style Manual: "The front of the leaf, the side t6hat lies to the right in an open book, is called the recto. The back of the leaf, the side that lies to the left when the leaf is turned, is the verso. Rectos are always odd-numbered, versos always even numbered." When submitting a book for publishing, I get an electronic proof copy back in Verso-Recto format, which makes it easy to check various formatting issues. It would be useful to be able to look for and correct these formatting errors before I submitted a manuscript to the publisher.
PS: you see the formatting effects in Print Layout mode also, not just when it is actually printed out.
Ask and ye shall receive.
Word already supports verso-recto formatting. Actually has for a long time. They dumbed it down, losing the latin and breaking into a couple of features, but it is all there.
At the end of a chapter go to Page Layout tab > Page Setup group > Breaks drop down > select "Odd Page" section break. That way, the next page, the first of the new chapter will ALWAYS, automatically, start on an odd numbered page.
You can also get to this feature by clicking on the dialog launcher button to display the Page Setup dialog. Click on the Layout tab then select "Odd Page" from the drop down. This will insert the Odd page section break.
While you are in this dialog, click on the Margins tab. In the margins section click in the Gutter box. Input a number to allow for the required binding gutter to be added to the "inside" margin.
The final step is to select duplex/2 sided print.
Eh viola <sic> you have Verso-Recto format.
Note: If you don't want to print to paper all the time, you can print to PDF (or XPS) and still have all of the verso-recto features.
