It's basically ready. I like to play with them for a while to make sure I like the way they work. I don't want to change my mind about it after releasing it because lots of people would get mad at me for making their fractals look different. I might change it yet, but I'm not sure.
You can try the development code if you want (no promises about the quality or compatibility with later releases!) The code is on the sourceforge svn server
