A powertoy from Jeff Cardon, one of the OneNote Testers…
Takes selected pages in OneNote and at the click of a button it will merge all of the pages together into one page.
A screenshot of what it looks like in the toolbar:

Some notes: there is a popup dialog which explains Undo is not supported. You can disable this dialog if you want, and I recommend disabling it as soon as you get comfortable with the implications that Undo is not supported. There is another warning if you merge more than 10 pages at a time. Again, you can disable this warning.
The reason I suggest disabling those warning are this is another managed code addin, so we cannot control focus of the confirmation dialogs. If you click the button and it looks like nothing happened, look “behind” OneNote to see the dialog. It’s easier just to live without the dialogs when you merge pages.
When installing, as usual, exit OneNote, run setup.exe and choose to install for all users.
