Subject: [PATCH] new toolbar mode: always_select when this mode is enabled, a
 toolbar item will always be selected. if the selected item is deleted, the
 next item will be selected. if there is no next item, the first item will be
 selected. if there is no next or first item, you can go <expletive deleted>
 yourself.
