I would appreciate an option to copy/move one or more pages between documents. E.g. right-click a page thumbnail in page preview, select cut/copy, then switch to the target document, then right-click at the proper location in the page preview and select paste.
Currently it seems that I have to extract the page(s) from document A, then merge the resulting files with document B, the re-order the pages in B as needed. This seems unnecessarily complicated.
