Now that we have a link to parent post, it would be nice to have a link to next subthread. Which is either our parent's next child or else the parent's next subthread. (With a root node's next leading where you want - the main forum is a reasonable choice.) I forget which of our many forums had it, but it works well for skipping around within a large conversation.
Cheers,
