GtkSidebar behaves internally much like GtkStackSwitcher, providing a vertical
sidebar like widget. It is virtually identical in appearance to the widget
currently used in GNOME Tweak Tool.
This widget is connected to a GtkStack, and builds its own contents as a
GtkListBox subclass, using the "title" child property to provide a consistent
navigatable widget.
Being a subclass of GtkListBox it benefits immediately from strong keyboard
navigation, and minimal changes are required for theming.

The child property is watched by the StackSwicther which in turns sets a
needs-attention css class on the corresponding button, so that the theme
can for instance show a throbbing animation if one of the hidden pages
needs the user attention.

Add separate GtkStack and GtkStackSwitcher widgets that are an
alternative to GtkNotebook. Additionally, GtkStack supports
animated transitions when changing pages.
These widgets were initially developed in libgd.
