I dont know if this should go in... unlike font and wps filenames, the
.cfg can be loaded from anywhere, so just assuming that it will be
loaded from the themes dir is a bad assumption. Also the fact that
changeing any "theme" setting will make the selection technically
wrong... and finally, there is nothing stopping you from loading two
theme .cfg's and have them work together.
There is a reason we dont save the theme filename and I dont tihnk
this should be changed.
