Tab Renamer

About

## Overview
A Chrome extension that allows users to assign custom names to tabs based on their URLs. The custom names persist across browser sessions and automatically apply when visiting the same URLs.

## Core Features

### 1. Interactive Tab Naming
- **Trigger**: Click the extension icon in the toolbar
- **UI**: Small popup window with input field and restore button
- **Behavior**:
  - For new URLs: Empty input field for entering custom name
  - For renamed URLs: Pre-populated with current custom name, editable
  - Press Enter to save and apply the custom name
  - Click "Restore" button to revert to original tab title
- **Tab Title Replacement**:
  - Custom names **completely replace** the original tab title
  - No concatenation or combination with original title
  - Short, clean tab titles as specified by the user
- **Example**:
  - User visits `https://github.com/user/repo/issues/1234/long-issue-title-that-makes-tab-unreadable`
  - Original tab shows: "Fix: Implementation of new feature system with multiple components · Issue #1234 · user/repo"
  - User clicks extension, enters "Bug #1234"
  - Tab now shows only: "Bug #1234"
  - The long original title is completely replaced

### 2. Persistent Storage
- **Storage**: Chrome's local storage API
- **Data Structure**: Key-value pairs (URL → Custom Name)
- **Persistence**: Survives browser restarts, profile syncing
- **Example**:
  ```json
  {
    "https://github.com/user/repo": "My Project",
    "https://stackoverflow.com/questions/123": "React Hook Solution"
  }
  ```

### 3. Automatic Tab Renaming
- **Trigger**: Page load/refresh
- **Behavior**: Automatically applies saved custom name
- **Example**:
  - User previously named `https://docs.google.com/document/d/abc123` as "Q4 Report"
  - Every time this URL loads (new tab, refresh, browser restart), tab shows "Q4 Report"

### 4. Duplicate URL Handling
- **Behavior**: All tabs with the same URL get the same custom name
- **Real-time sync**: Renaming one tab updates all tabs with that URL
- **Example**:
  - User has 3 tabs open with `https://mail.google.com`
  - Names one tab "Work Email"
  - All 3 tabs immediately show "Work Email"

### 5. Subdomain/Path Inheritance
- **Pattern Matching**: URLs with additional path segments inherit base name with suffix
- **Format**: `{custom_name} - {additional_path_info}`
- **Examples**:
  - Base: `https://example.com/docs` → "API Docs"
  - Inherits:
    - `https://example.com/docs/authentication` → "API Docs - authentication"
    - `https://example.com/docs/api/v2` → "API Docs - api/v2"
    - `https://example.com/docs/guides/quickstart` → "API Docs - guides/quickstart"
