Translatable title and page path

I'm using this module on a Multilanguage website in Dutch and English.

The module works great! In Dutch, the main language of website, everything works fine. On the English website the English terms are displayed and that's links are working fine. Still I have two problems.

1. I can't translate the title of a vocabulary.

On line 320 I added the t() function
drupal_set_title(t(check_plain($vi->name)) . ' » ' . drupal_strtoupper($output['letter']));

This solves my problem and now I can translate the vocabulary title with translate string.
So in Dutch the title will be "Trefwoorden » letter" and in English it is "Keywords » letter"

2. What would be nice in is that you can set different url paths for the different languages. So in Dutch the path will be "onderwerpen/trefwoorden". But on the English website you don't want the Dutch path in the url. So if you can set another path for example "subjects/keywords" that would be much nicer.

Or maybe there is another way to change the url for multilanguage website including the letter behind it?

Thanks
