Thanks. For what it's worth, I was trying it in the hope that it'd do something different: I want to keep the enabled nodelets as brief as possible, so I was hoping the Nodelet Nodelet would either show the selected nodelet in a full page as if it were a node, or show it as a nodelet but temporarily (a one-shot enable) so that I could still find back things like the 'Leftovers' links when I needed them.
