The easiest way to do that is to just do:
'exclude' => '5,12'

You can exclude how ever many you like just by using a string of comma-separated id’s. Talks about it in the get_terms reference.

Hope that helps.

The only way I figured out to do it is to go into widget.php in the plugin directory.

On line 142 it uses the get_terms function, so you can alter the term list however you like.

To exclude a specific category, just change that line to:
return get_terms( $tax, array('exclude' => 4)); // change 4 to whatever category id you want removed

Hope that helps.
