Ok, let's create a "Litestep" folder in the "$DocumentsDir$" and let's put into it the regular "$LitestepDir$step.rc".
The regular "$LitestepDir$step.rc" should only containt this line:
Include "$DocumentsDir$Litestep\step.rc"

Now, themes that want to be "X-OTS" compliant have to deal with this to let users change themes without disturbing others...

If everyone ok, we will talk about serious things when I had sleep a while...
