Ask HN: Would this improve reading experience on HN?

Sometimes I find topics with alot of comments to be disconnecting when I'm going through the comments. Especially when there are multiple replies within multiple replies, it can be tricky to follow the conversation and understand the comment's context.

Made a quick sketch of a hover action that would show the comment that it is replying to, to put the comment in context. Think it would help the comment reading experience?
