Hi Maksim,

This is not possible by default, but it is possible by changing the value with our ac/column/value filter.
You can use the following snippet in your code to make the permalink a link with an eye icon as label.

/**
 * @param $value  string
 * @param $id     int
 * @param $column AC_Column
 */
function ac_column_permalink_icon( $value, $id, $column ) {
	if ( $column instanceof AC_Column_Post_Permalink ) {
		$value = ac_helper()->html->link( strip_tags( $value ), '<span class="dashicons dashicons-visibility"></span>' );
	}

	return $value;
}

add_filter( 'ac/column/value', 'ac_column_permalink_icon', 10, 3 );

You can find more information about the used filter here:
