I added a new style called "simple" to the site. Its aim is to simplify the interface to address some previous requests. Constructive suggestions for improvement are welcome.
To load the new style, go to the bottom of any page and in the lower left in the menu bar there is a drop-down list with available styles. Select "simple" and the new style will load automatically. Doing this sets the selected style as your default permanently, so if you want to go back to the Default style, you will need to manually switch back to it.
