I have no idea how feasible this is, but I think it would be a neat feature. What about adding some additional things to the sidebar menu? I use the dragon skin so I don't know if there is more on the other one, but I especially think it would be cool to have a link on the sidebar menu for our favorite stories and authors. Right now I go through Account Info and that's fine but a more direct link might be cool.
Just an idea!
That does sound like a good idea. Maybe a few customizable slots on the navbar for us to put links to stories/pages that we want to quickly access.
