Feature Request: Subtitle span text without href

A feature request: I have CSS transitions applied to the menu link and when I use your module it inherits the padding, which skews the size. I worked around this by specifying the CSS more, but there is still a lack of transition effect when I mouseover the submenu link.

Is there any way to make the submenu link only text and not a HREF? I would love it if it was just Subtitle text.

I have found a temporary work around in your module though adding this as a feature with a toggle box on each menu would be very convenient.

Here is what I changed, line 131 in menu_subtitle.module
From
$output .= '<span class="menu-link-subtitle menu-link-subtitle-below">' . l($subtitle, $element['#href'], $element['#localized_options']) . '</span>';
To
$output .= '<span class="menu-link-subtitle menu-link-subtitle-below">' . $subtitle . '</span>';

Thanks for the great module!
