[Plugin: Query Multiple Taxonomies] Change name of "title" category taxonomy

Hello,
I’m using two taxonomies: one called City, the other one called Stars. Apart from these two taxonomies I also display the list of categories.
I’m using the plugin directly in the code. So, here it goes:

<?php the_widget('Taxonomy_Drill_Down_Widget', array(
  'title' => '',
  'mode' => 'dropdowns',
  'taxonomies' => array( 'city', 'star', 'category' ) // list of taxonomy names
	));
?>

This displays the following:

• City : Dropdown
• Star : Dropdown
• Category : Dropdown

I want to change the way Category is displayed. I want to put another title for the categories. I want it to be: [ XXXX (instead of ‘Category’) : Dropdown ]

How can I do that without transforming all the WordPress code? Do I have to recreate a specific taxonomy? I hope it’s clear enough. If you need more explanation, just let me know.
Also, inside the categories list, is it possible to exclude a specific one?

Thanks in advance for your answers!
