Hmm I think it would be possible pretty easy for the pmdev-crew, but I wonder if it's really useful.
I think it would be nice to have "new, yet unanswered questions", in a nodelet but not all new nodes or questions. I would love it for the questioner to have a checkbox "I know now what I wanted to", and then have only those new ones displayed that haven't been answered in a good way yet.
But currently I'm pretty happy with having the newest nodes which I can refresh pretty nicely and set my "stamp" etc...
