This was a fun project to work on, and a great place to learn, but, with the X developers phasing out the xorg.conf, and only the nvidia drivers (which work better with nvidia-settings anyway) the only major remaining hurdle, it just isn't needed anymore. That was the main reason why development stopped, there was no point doing something that would be dead in a year.
Life sucks like that,
XMCE, an xorg.conf configuration editor. This release is stable, but early. It is english only at present, however, we are hoping to change this, if you are interested or have any comments at all, please do feed back to me and my apprentice/team.
