Like he said, but also done with kde.
The gui is just a handler for the *.conf files.
Simmillarly, old files may be renamed filename.tla~
These can be read with any text editor.
Most times permissions or a double switch somewhere can undo all the good work.
If you experiment, like me, take notes (please).
I have a list of files worth backing up when they work.
If you want I can post it here.
