I 'feel' like I may not know everything you're wanting to
By, 'small', do you mean 50 pages, 100 pages?
How about each page gets an id that will put it in the proper
order when it is appended to a list and then sequenced through?
Start out with id's that are, maybe 10 numbers apart so that you
can easily insert pages in the sequence with out renumbering the
other pages. Or you could just as easily use your 'seq' property.
Create and append to a list each of the pages sorted by id. Then
your NEXT PREVIOUS links will be to; sequence-index +1 and
sequence-index - 1.
