disable navbar items

[fobster]

I was looking in the navbar template and I see this

if condition="$show['member']">
<td class="vbmenu_control"><a href="usercp.php$session[sessionurl_q]">$vbphrase[user_cp]</a></td>
</if>
<if condition="$show['registerbutton']">
...

which leads me to believe I can disable navigation items from the admincp (what in the admin cp controls what goes into $show). Is the only way to disable the default navigation items to edit the template? or is there a admincp option that controls what is displayed in the navigation?
