Well, I tried to design it so that much of the time you can just fill in what you are searching for in that first box and then hit the button. But there needs to be some major work on how the results are presented after that.
As I mentioned in the announcement, you can't search "newest first" yet. Those radio buttons are supposed to be "disabled" (they show greyed-out in my browser). I'll probably just remove them until (if) I get
that part working. (And the "starting at node ID" field will probably disappear as well.)
Yes, customizing order on Newest Nodes has been discussed and will probably happen at some point. (:
