About

**GitHub Reactions Minimap**

Visualize the signal in long GitHub discussions - instantly.

GitHub Reactions Minimap augments issue and pull request pages with a scrollbar overlay that highlights where reactions are happening. Instead of scrolling blindly through hundreds of comments, you get a compact, color-coded map of activity.

**How it works**

* Adds markers to the scrollbar for every comment with reactions
* Colors reflect "karma" so you can quickly spot high-signal or controversial threads
* Highlights comment borders using the same color scheme for easy scanning in-page

**Why it's useful**

* Jump directly to the most relevant or debated comments
* Avoid wasting time on low-signal discussion
* Get a quick sense of community sentiment across large threads

**Features**

* Scrollbar minimap with reaction-based markers
* Karma-based color coding (positive = green, negative = red)
* In-page comment highlighting
* Lightweight and fast - no page reloads or heavy processing

Designed for developers who live in GitHub and want faster context, better signal, and less scrolling.
