Is a big problem: when moving pages from different Documents with the same options, master pages and Layouts the pages moved are shifted (to the left or to the right).
I've made an Example in the attached Files.
1.png shows the way I move the last two pages of the document to the other document (identical copy of the same file).
2.png shows the pages moved in the second document (they should be the same but the imported ones are shifted by a few millimeters).
For documents where you have to import hundreds of pages it is very frustrating to have to manually rearrange them all.
