Is it at all possible for the Next Topic and Previous Topic links use the UNREAD anchor or am I misunderstanding how it works?

IIRC the unread anchor is set via php when threads are spewed out based on the log of yoru last visit; I'm not entirely sure how it works but keep in mind that there can sometimes be several pages of unread content and it'd suck for it to link to your previous/next as it'd skip over content...
