Ability to exclude a taxonomy from Vocabularies list

Thank you for this excellent module! I have a minor feature request. In the Taxonomy Browser module there is a select list for specifying "Included Vocabularies". I have two vocabularies, but I only want VocabIndex to show one of them. I was able to hack this in the .inc file by commenting out lines 11-13 and then adding the following:

drupal_goto('taxonomy_vtn/voc/1');

Ideally, however, this module would provide a UI similar to Taxonomy Browser for including/excluding taxonomies.
