hello kiwidude,

i'm wondering if its possible to add some sort of group limit to extraction?
i tried selecting all books but it will take to long to finish, the group limit will group the queues into 10, 20 or 50 (depends on how powerful the computer).

e.g.

1. library 5000 books with no identifier
2. using identifiers:"=false"
3. select all the books
4. extract isbn (group into 10 - slow computer/usb2)
5. 5000 books = 500 groups (groupings could be similar to find duplicate)
6. translate to 500 jobs
7. --go to work - shut down computer--
8. check calibre-jobs for what group you are in (N)
9. close calibre
10. --start calibre--
11. extract isbn from group N to group N

something like that, is that possible? it will prevent calibre from hanging.

thanks
