Restrict the contact form only on desired content type, set width and height inside block

Hello
Instead of adding some code, should it be a feature added like in the author_pane block to display a check list of allowed content type to display the form ?
thanks

finally i just made it :)
thanks to michelle works in author_pane

i've also added to select in the block the width form name/email and the height for the message

could see result here http://immo-g-meyer.fr and look at an house to have the form displayed

here's the code i change in authorcontact.module

 function authorcontact_block($op = 'list', $delta = 0, $edit = array()) {
    switch ($op) {
        case 'list':
            $blocks[0]['info'] = t('Author Contact');
            return $blocks;
        
        case 'configure':
            $form['authorcontact_desc'] = array(
                '#type' => 'textfield',
                '#title' => t('Contact description'),
                '#description' => t('This text will show at the top of the Author Contact block, can be used for instructions etc.'),
                '#default_value' => variable_get('authorcontact_desc', '')
            );

            $form['authorcontact_form_width'] = array(
                '#type' => 'textfield',
                '#title' => t('Form width for name & email'),
                '#description' => t('You can set here the size of the form width without change in the css #edit-sendername, #edit-senderemail, #edit-sendercomment {width:94%;} '),
                '#default_value' => variable_get('authorcontact_form_width', 15)
            );
            $form['authorcontact_form_height'] = array(
                '#type' => 'textfield',
                '#title' => t('Form height for message'),
                '#description' => t('You can set here thenumber of line to dislay in the message form. Standard is 4.'),
                '#default_value' => variable_get('authorcontact_form_height', 4)
            );

Thanks for the code elarifr, I'll review this and add it into the dev of the module.

+1 for this in DEV.

Thanks.

Now committed to 6.x dev version - thanks for the code Elari
