MidCOM: Request for Feature (RFF): add "in_index" attribute to data schema

Hi,
 
I've just faced a small issue when biudling a site. I need to have some
particular fields from data schema to be visible in "autoindex" mode with
taviewer and "latest" mode in newsticker. How about adding "in_index"
atribiuute to a filed definition so that viewer mechanism could add those
fields into index or latest results. Something like:
 
"personel" => array (
    "name"        => "personel",
    "description" => "Personel",
    "fields"      => array (

        "image" => array (
            "description" => "Fotka",
            "datatype"    => "image",
            "widget_image_simple" => false,
            "datatype_image_thumbwidth" => 101,
            "datatype_image_thumbheight" => 101,
           "in_index"=> true,

        ),
     )
)
 
In this case viewer class would pick only required and in_index fields and
store them in $view array.
