Also, would be nice to have on the printed page extra info. It just has line numbers and at bottom of page is the page number. I'd like to the right of the line numbers 1 character of my chooseing to be printed. Say, on the first set 'A' and the next time I print out a "B". That way O can print out multiple times and have a way of quickly knowing what pages belong to what set.
1A
2A
3A
...
next time I print out
1B
2B
3B
....
then I can quickly look and see what pages go together.
