A short template that allows to merge odd and even pages together, considering also the case of the reversed even pages. As usual there is a little edit area that make the process very fast, without requiring any knowledge of LaTeX.
Read me:
Load your PDFs (Project --> files)
the PDF that contains odd pages
the PDF that contains even pages
Change opportunely the size and the number of pages
Specify if the even pages are reversed ("1") or not ("0")
