Bug Description

Binary package hint: simple-scan

Maverick, 32 bits, all updates installed.

I'm often scanning documents that are double sided, on a scanner with sheetfeeder but no duplexer (HP c7280).
This means I scan the entire batch first odd pages, get them out (including pulling the last page out which is stuck somewhere halfway out of the scanner) reload them in the feeder and scan all even pages.

After scanning all pages I have to reshuffle all odds and evens with the < and > keys to get the order right.
>>> Wishlist: a 'sort pages' option to interlace 2 runs of scans. A bit like some programs / printer drivers offer in order to get double sided printouts when you use a printer that has no duplexer. First you print all odds, then reload the output into the printer again (upside down and back to front somehow) and then print the even sides on the backs.
Would be a great help.

Some options:
 * A Scan>Scan Backs option that does an ADF scan but inserts the B pages in the correct order.
 * Another "Scan Side" preferences - "Front and Back (two step)". In this case when the last page is scanned the user is prompted to reinsert the pages upside down and continue. The pages are correctly stitched together. This may be less discoverable than the first option. Putting a link to the preferences in the scan dropdown could solve this?

Mind you, if I scan as decribed above I keep the stack in its original order when putting it in the sheet feeder again, so the second run (back pages) goes from the high numbers down.
The order of pages in simplescan is thus F1F2F3F4F5B5B4B3B2B1 F=front, B=back (not F0F1F2F3F4B0B1B2B3B4 as in #660253)
It's a minor issue sorting-wise but the stitching must take this into account of course, not to defeat its very purpose.
