I don’t think that many people are going to use this feature so I won’t get it into the plugin.
That being said, you can totally do this by yourself, here how :
method 1 :
go into the plugin folder /css/agent-admin-style.css
add this rule and save:
div#contextual-help-link-wrap {
display: none;
}
Note that this will be removed if you update the plugin in the future.
method 2:
go in to your theme folder and open styles.css
add the same rule and save.
Note that this will be removed if you update or replace a theme in the future
It is better to do this in a child theme if you are working with one.
method 3:
go into your functions.php and add this rule:
// Hide admin help tab
function hide_help() {
echo '<style type="text/css">
#contextual-help-link-wrap { display: none !important; }
</style>';
}
add_action('admin_head', 'hide_help');
Note that this will be removed if you update or replace a theme in the future
It is better to do this in a child theme if you are working with one.
Good luck
