Dashboard is an application for Apple's Mac OS X v10.4 Tiger operating system, used for hosting mini-applications known as widgets. It is a semi-transparent layer that is invisible to the user unless activated by a hotkey, which can be set to the user's preference.
When Dashboard is activated, the user's desktop is dimmed and widgets fade into the foreground. Like application windows, they can be moved around, rearranged, deleted, and recreated (so that more than one of the same Widget is open at the same time, possibly with different settings). New widgets can be opened, via a menu bar, by dragging their icon out into the layer. After loading, the widget is ready for use.
