Aside from the javadoc warnings, I'm not aware of any great effort needed
to port tonegodGUI to 3.1.
Part of my hesitation to work on tonegodGUI comes from the fact that
tonegod's coding style is so different from my own. Every time I look at
her code, I feel the urge to convert it in my own peculiar style, but that
would make it difficult to compare my fork with other forks.
Plus I keep hoping she'll return to the project, in which case my efforts
would be better directed elsewhere.
