# WhatsApp Heart Favorites
<!-- ✅ -->
A Chrome extension that automatically stars messages when you react with a heart emoji on WhatsApp Web.
## Description
<!-- ✅ -->
WhatsApp Heart Favorites enhances your WhatsApp Web experience by automatically starring messages that you react to with a heart emoji (❤️). This makes it easier to keep track of important messages without having to manually star them.
## Features
<!-- ✅ -->
- Automatically stars messages when you add a heart reaction
- Works seamlessly with WhatsApp Web
- Lightweight and unobtrusive
## Installation
### From Chrome Web Store
1. Visit the Chrome Web Store (link to be added)
- [Chrome Web Store](https://chrome.google.com/webstore/detail/whatsapp-heart-favorites/your-extension-id) (TODO)

3. Confirm the installation
### Manual Installation

5. The extension should now be installed and active
## Usage
<!-- ✅ -->

## How It Works
<!-- ✅ -->
The extension injects a script into WhatsApp Web that:
1. Accesses WhatsApp's internal JavaScript modules

3. This new callback triggers the star message function

## Development
