D2Tool - Dota 2 Hero Grid Tool

D2Tool is a desktop application that helps you manage your Dota 2 hero grid configurations. It automatically updates your Dota 2 heroes grid config files periodically in the background, organizing heroes based on their performance data from Dota 2 Pro Tracker.

Features

• Automatic Grid Generation: Creates hero grid layouts based on hero ratings and match counts from Dota 2 Pro Tracker
• Position-Based Organization: Organizes heroes by their positions (Carry, Mid, Offlane, Support, Hard Support) with customizable order
• Multiple Account Support: Automatically finds and manages grid configs for all Steam accounts on your computer
• Per-File Management: Enable/disable individual config files, view last update time and errors for each file
• Position Toggle: Enable or disable specific positions to customize which roles appear in your grid
• Drag & Drop Reordering: Easily reorder positions by dragging them in the interface
• Background Operation: Runs in the background and updates grids periodically (every hour)
• Auto-Updates: Automatically checks for application updates on startup and periodically
• Startup Integration: Option to run automatically when your computer starts (Windows only)
• System Tray: Minimizes to system tray when closed (Windows only)
• Modern Interface: Clean, dark-themed UI with sidebar navigation

How It Works

D2Tool fetches hero statistics from Dota 2 Pro Tracker, then:

1. Finds your Steam installation and locates all hero grid config files
2. Removes any previously generated D2Tool configurations
3. Creates new hero grid layouts organized by enabled positions and performance metrics
4. Saves the updated configurations back to your Dota 2 config files
