Hi, It would be very nice if the settings manager would display all settings icons (like any other desktop environment does) for example my Package Manager(Synaptic) is tagged as: Categories=PackageManager;GTK;System;Settings; an there is a System section in the settings manager so it would only make sense to display them there other examples would be the Flash Player settings: Categories=Settings;GNOME;GTK;X-GNOME-PersonalSettings; or Obconf Categories=Settings;DesktopSettings;GTK; Also by moving them into the settings manager, the weird "Settings" submenu could be replaced with a simple link to the settings manager.

Yup, it is up to distributions.
