Link translated terms automatically in hierarchical taxonomies

Dear developers,
thank you very much for providing the i18n features. I'm new to drupal and testing a lot of modules and stuff.

My current problem is with hierarchical terms and translations. Think of a structure like is:

Current:

• t1.en
  • t2.en
  • t3.en
• t4.en
  • t5.en
• t1.de
  • t2.de
  • t3.de
• t4.de

Now, when I translate t5.en to German, I get a new term added on root level to the vocabulary. But, from my point of view, drupal should know, that t5.de is a sibling of t4.de. See the following listings:

Expected:

• t1.en
  • t2.en
  • t3.en
• t4.en
  • t5.en
• t1.de
  • t2.de
  • t3.de
• t4.de
  • t5.de

Received:

• t5.de
• t1.en
  • t2.en
  • t3.en
• t4.en
  • t5.en
• t1.de
  • t2.de
  • t3.de
• t4.de

Feel free to ask for comment on this. I hope this helps to improve drupal.

Kind regards,
Eike
