AppInfoManager - A singleton class that caches
GLib.AppInfo objects. Singletons are evil, yes, but this on slightly less so because the exposed API is immutable.
DeprecatedScopeSearch - Internal
transitioning class, note that it will disappear from the public API as soon as possible and therefore shouldn't be used.
Inspector - The Unity.Inspector is a singleton that can
be used to inspect the state of Unity.
LauncherEntry - This class represents your control
point for your application's icon in the Unity Launcher. You can control properties such as a counter, progress, or emblem that will be
overlaid on your application's launcher icon. You can also set a quicklist on it by setting the "quicklist" property to point at the
Dbusmenu.Menuitem which is the root of your quicklist.
