I find the “new” badge for new topics very handy, partly in order not to miss those topics. However, if a new topic consists of one post only, this “new” badge is not shown. In the past, this has caused me to miss topics. So again, I don’t know how much work it is, but if it is not too difficult, also adding the “new” badge to new threads containing only one post, would be very handy IMHO.
