The best feature of Newest Nodes is in your browser: the nodes you haven't seen yet, have a different colour.

I tend to use 3 or 4 computers during the day, and pop into PM throughout the day. Browser link coloring is of little use to me. I find that I have to remember root node titles to keep track of this.

An age indicator would have more usefulness.
