As a Windows/Linux user without access to macOS, I came across this post yesterday — Show HN: A native macOS client for Hacker News, built with SwiftUI ( https://news.ycombinator.com/item?id=47088166 ) — and found myself envious of the experience it offered: card-based layout, split-pane reading, and a cleaner way to browse stories.

So I worked with Claude to replicate the key features as a Tampermonkey/Greasemonkey userscript. Here's what it does:

  - Replaces the default HN listing with a responsive card grid
  - Fetches og:image thumbnails lazily as you scroll (falls back to favicon + domain)
  - Split-pane reader: article on the left, HN comments on the right — no tab-switching
  - Draggable divider to resize the two panes
  - Swap button to flip article/comments sides
  - Inline article rendering that inlines external stylesheets to work around CSP restrictions
  - Algolia-powered search bar
  - One-click toggle back to the classic list view
  - Persistent thumbnail cache via sessionStorage

Happy to hear feedback — particularly around sites that block iframe embedding or break the inline stylesheet loader.
