I'm learning Processing by going through some of the Processing tutorials and the problems in The Nature of Code (using Processing v2.0b7). While the PDE is certainly useful, the default color scheme strains my eyes. I spent a significant amount of time googling for PDE color schemes, but the closest result that I could find was a feature request from 2010 that calls for editing a configuration file that doesn't seem to exist in version 2.0b7. Also, there are no color theme options in the preferences (only font size).

Has any progress been made towards new color schemes for the PDE? If possible, I'd like zenburn (as depicted here), but I'd happily accept justabout any medium-to-dark background color scheme.
