@moonman I could probably actually write something to do this into postActiv.  It wouldn't be difficult, but it would be a little time consuming.  It would cause weirdness in Qvitter though since it displays notices in the order the API sends them, which is NOT chronological.  So for instance if you had a notice that was older, the OP say, but it got the child posts and not the OP, then you would actually get the OP after the two replies, because it was fetched more recently.  This isn't some unsolvable technical paradox, but it does present a problem.
