I once did it. I remember I edited some script file to make it happen but I forgot what and how it was done. Could someone help me in that direction? This is for my friend who has an serious eye problem and he needs to have the curtain on all the time..
I have searched in default.jss but that file seems to change a lot from my last visit in it.
