[horde] imp - menu

[Martin Hochreiter]

Hi!

I have added the following code in imp/config/menu.php to get
a new icon in the menu.
I want to open the link at least in a new window - better would
be a javascript "onclick" event but both options (target and onclick)
are ignored

below my version of the "at least" - non working version:

$_menu = array();

/* Add your custom entries below this line. */

  $_menu['passwort'] = array(
        'url' =>        'https://www.domain.tld/dienstplan/chpwd.php',
        'text' =>       'Passwort',
        'icon' =>  'passwd.png',
        'target' =>     '_blank',
    );

any ideas?
