The "Widgets" page in an XCenter settings notebook allows you to view and modify the widgets in that XCenter. For an introduction about the XCenter and widgets, see this page.

The widgets are listed in a details view, with the XCenter's leftmost widget on top in the list. Note that you can drag and drop the items within the list to change the order of widgets in the XCenter bar.

The "Class" column displays the internal widget class name. (Note that widget classes are not true WPS classes. Only the XCenter uses the class names to organize widgets internally, but the concept is somewhat similar, hence the name.)

The "Setup" column shows you the current setup string of the widget. Even though widgets are not WPS objects, they save their setup internally with setup strings similar to those of the WPS. This allows the XCenter to combine all widget setup strings into its own WPS setup string so that an XCenter can be recreated identically somewhere else.
