AI Analysis

●●SolidNiche GemCozy

Drill-down comment navigation beats endless scrolling on HN threads.

Strengths

•Reconstructs comment tree from HN's flat HTML rows using indent values — no API needed.
•Markdown rendering with DOMPurify keeps comment formatting intact and secure.
•Shows/hides existing HN rows so voting, timestamps, and reply links still work.

Weaknesses

•Chrome-only; Firefox and Safari users can't install this extension.
•Solves a preference problem that most HN readers don't find painful enough.

Post Description

I prefer to read the HN comment threads in a drill down way instead of having all comments expanded. Also I do not enjoy the tiny (-) to collapse a thread. This extension make reading comment easier for me.
