The more possible options are implemented to suit every single user's 'needs', the more you end up with a system like KDE, where you can almost literally configure the behaviour of every pixel, but no matter which configuration options you choose, it never works well/looks good. If you like using such an incredible mess of a system, I don't know how to help anymore.

If the defaults aren't sane, not even a million configuration options will make it better. If you think a certain behaviour is clearly better than another one, and you can demonstrate this and explain why, that behaviour should be the default, and there should be no option to have it any other way.
