I just added this under $threadbits_sticky and it adds the little down arrow in the last column:
Code:
<tr><td class="thead" colspan="<if condition="$show['threadicons']">6<else />5</if>"> </td>
<if condition="$show['inlinemod']">
<if condition="$show['popups']">
<td class="vbmenu_control" id="imod" align="center"> <script type="text/javascript"> vbmenu_register('imod'); </script> </td>
<else />
<td class="thead" align="center">
<input type="checkbox" name="allbox" id="checkall_all" title="$vbphrase[check_uncheck_all]" onclick="inlineMod.check_all()" />
</td>
</if>
</if>
</tr>
