There are much tools out there to tweak your ubuntu desktop. I think most of you are knowing tools like "Unsettings", "Ubuntu-Tweak", "Gnome-Tweak-Tool" and "MyUnity". I like this tools, because sometimes i like changing some behavior or the Look and Feel of my Desktop. I like to personalize it. So, thanks to the developers who programmed this tools. But i am asking myselfe why there isnt an integration in "SystemSettings->Appearance".
