Ask me for any improvement on the Hacker News Navigation

Hi guys; some days ago i published a Google Chrome extension that adds some functionalities to the navigation through this site (Hacker News).

If you are a Chrome user an have an idea for a feature that you would like to see implemented in the HN navigation please tell me about in this thread.

So far it have 3 features/changes:

1) It adds the button "parent" in every (child) comment, when you put the mouse over it highlights the parent comment. When is clicked it brings the parent comment closer to the child comment, this is especially useful for when you cant see the parent comment because is too far away.

2) It also changes the title; so it becomes "$TITLE | Hacker News" instead of the current "Hacker News | $TITLE"

3) You will never get again the "Unknown or Expired Link" message. Always the valid and correct link to change the page.
