Of course you can change the files that you need, it would be ridiculous if not.
What I mean is about the Suse philosophy behind configuration. Everything should be X oriented through whatever tool, they almost do not document the way via command line, simply because they think users don't want to handle command line.

This is Windows philosophy and Suse follows that. I don't think this is wrong, IMHO I think this is necessary for the good sake of Linux -- perhaps the single change against Bill Gates.

Unfortunately, sometimes is pretty easy to do things via command line and get very annoying when they changed that in order do provide an X solution.

Don't mind, I'm just a 28 years old Linux user since Red Hat 5.
I wander I may be too old now...
