Windows 10: Backing up OneNote?

Are you talking about dragging and dropping the tabs, like in a browser? The pages on the right can be D&D'd too.

 

No. The tabs ( or sections) on top are fine and can be dragged to any order. And yes, individual pages can be dragged to any order. All that's fine.

I am talking about the main windows. In OneNote2016. its the opposite of what It should be. I am looking at it now and there is content on the left pane, and a menu of pages on the right. I would like it reversed, so its like all the other OneNote apps I am used to, where the menu of pages is on the left, and the content is on the right.

 

Found it. It was buried here with the default unchecked ! :
File/Options/Display check box for "Page Tabs appear on the left"

 

I know what you're talking about now. No It doesn't look like you can switch sides, just shrink and expand.
