Create a Duplicate of Every Page Next to the Original Page

[woodified]

I am looking for a way to duplicate pages where the duplicate is placed next to the original. I have a PDF that are scans of a book, but each PDF page is currently two book pages. I would like to duplicate each page and then crop the original and duplicate so that each PDF page corresponds to a book page.

If I select a group of pages I see that I can place the duplicates before or after the selected group, but is there a way to have each duplicate appear right after the page it is copying?

Hello, woodified

The simplest way I can think of to do this would be with Javascript. I do not have a sample on hand to perform the whole process, but I do have part of it available.
Below is an interleave page tool:

Interleave pages A1B1.zip

Simply unzip this and place the Js file in the following folder under your Editor install directory (then restart the Editor):
C:\Program Files\Tracker Software\PDF Editor\JavaScripts

Once you have done that, open the file in which you wish to duplicate pages. From the Thumbnails pane, select all (Ctrl_A), Copy (Ctrl_C), and immediately paste (Ctrl_V) to duplicate the pages. You should see something like this:
Before:

After:

Following that, on the Add-on tools tab, use the new "interleave A1,B1,A2" button, to get the desired final result:
