Question: How to show the action and subaction on the Who is Online screen if the action is unkown.
Some user admin like to know what some guest use as unknown action

. With this small change you can see this.
Search in the $sourcedir/Who.php for
else
$data[$k] = $txt['who_unknown'];
and replace it with
else
$data[$k] = $txt['who_unknown'].
($user_info['is_admin'] ? (
(isset($actions['action']) ? ' <span class="smalltext">('.$txt['who_action'].': '.$actions['action'].
(isset($actions['sa']) ? ' -> '.$actions['sa'] : '').')</span>' : '')) : '');
Than after the "unkown action" stand for admins (Action: ACTION -> SUBACTION (if exist)).
This should work in SMF 1.1.x
