Removing tabs all together

Hi,
Great plugin.
I was just wondering how I could remove the tabs all together?
I only wish to use the widget as ‘most viewed’ at this stage, so having just one tab sitting there is kind of useless.
Can I just remove the code in the files?
Codes such as the four of these maybe? Or will that leave a blank space at the top?

//most comments
if( empty( $norecent )){
$output .= ‘number.'”>’;
$output .= $this->functions->get_recent_posts( $instance );
$output .= ”;
}
