Address Box:
You know that little text box on the right side of every page where you can just type the wiki-name and go? It would be nice to have that feature for the writings, too.

Your Writings Button:
Just like the "Your Presentation" button, this would make navigation quicker as you wouldn't have to go through your presentation to get to your index (then again, so would the superwiki address box, so maybe if you implemented that, this would be unnecessary).
