why not making plugin functions pluggable?

Hi, I use the templatesnet toolkit with i-excel and i-craft theme.

in the shortcodes.php file of that plugin, there is that function:

function tx_blog_function($atts, $content = null) {
   	$atts = shortcode_atts(array(
      	'items' => 4,
      	'columns' => 4,
      	'showcat' => 'show',
      	'category_id' => '',
		'show_pagination' => 'no',
      	'carousel' => 'no',
   	), $atts);
	$width = 600;
	$height = 320;

and on every update, I have to re-edit it to change height (I have square icons).

why not making that plugins functions pluggable? a simple if function exist could be the solution
