I do not want the wiki menu to be displayed to anyone except an 'admin' and I hope that this option will eventually become available.
Until then, this is my workaround solution:
Create a view for the wiki controller function. Place inside that view
this script:
{{if not auth.has_membership('admin'):}}
<script type="text/javascript" >
$(document).ready(function() {
$("a:contains('[Wiki]')").closest('li').remove();
});
</script>
{{pass}}
Maybe this would work for you too.
