Userscripts.org

As to the width of the left nav pane, I have found that it does not adjust to accommodate contents. Therefore, this script has a tendency to truncate display of some of my labels.

I discovered a work-around myself by editing line 86 the script and changing the value below from 150px:
navPane.style.width = '170px';

If there is not a feasible way to determine the appropriate width dynamically, I would nominate this higher value for the pane width.
