There is a new CAPI facility for making a toolbar, which is typically displayed at the top of the window. On Cocoa, this makes a standard foldable toolbar. The user can use a customization dialog (via the context menu) to choose which items appear on the toolbar. See the
toolbar-items
,
toolbar-states
and
default-toolbar-states
initargs for
capi:interface
and the functions
capi:interface-toolbar-state
,
capi:interface-default-toolbar-states

and
