Version: 4.4_rc2 / 4.3.95 (using Devel) Compiler: gcc 4.4.2 Gentoo 4.4.2 p1.0 OS: Linux Installed from: Compiled sources The destinction between the "Desktop" and "Appearance" systemsetting modules is certainly not clear. I always have to guess where to search and often enough I choose wrongly. Most prominent examples are desktop effects and screensaver. I do not understand why they are specific to the "desktop"... Desktop effects deal with a lot more than just what the average user might see as the desktop. It's window animation and transparency and all such things.
