Hacker News: Show Parent Comment

In HN threaded comments, easily see which parent a comment was answering to

Threaded comments are useful to allow sub-discussions, but they are sometimes difficult to follow: In long and complicated threads, did you ever wonder what was a given comment answering to? With this extension, when a comment's parent isn't right above, you will see a "show parent" menu item. Just hover your mouse on that item, and the parent that comment was answering to will be shown right above it. Enjoy!
