I have a wide screen monitor and I have plenty of Gray area as you can see from picture on right.

I wonder if I can add some notes or text boxes there? (Just like I did from photoshop) Once I saw a guy using Adobe InDesign in which he could have such an option. He removes, adds pictures, formatting, important notes on right and these notes stay next to related page.

So, does Word have such a feature? It would be so useful
