I was happy to find this plugin as I was formerly using the normal
'previous_post_link function' with pages that was rendering strange order (by date?)
This one seems work much better, however I don't seem to get the full loop...
For example, this 1st subpage of 'history' does not manage to find a previous page - it should be parent though. I don't know why...
And this last supgae of a section can't get to the next section
Is it because I have not ordered my pages correctly? What is theloop normally based on?
