DesktopX is nearing release after nearly a year of public testing and even longer of internal development.The new version fixes bugs and adds a host of new features not the least being having persistent objects (objects that you can choose to stay between themes).
DesktopX is the ultimate shell extender. It's not a shell, it makes Explorer or Litestep or whatever have an object oriented theme model.
