double sided scanning
It would be great if there was a way to create a .pdf from doublesided documents without doing each page manually or having a scanner that does it automatically. Ideally, I would scan the odd pages. Then turn the stack of documents over and scan the even pages. Then reverse the even pages (to go from low page number to high). Then combine the odd and even pages in a way that it will be: 1,2,3,4,5,6, etc

One possible implementation would be to be able to mix pages of two documents, first to become the even pages, the other to become the odd pages.
(a1, a2, a3 ) + (b1, b2, b3) = (a1, b1, a2, b2, a3, b3)
