// // ===============================================================================
// // HierarchyEnhancer - Quick Toggle for GameObjects
// //
// // Creator: Scove
// // Last Updated: 2024-05-08
// // Version: 2.0
// //
// // Purpose:
// // Adds a handy toggle checkbox to the right side of every item in the Hierarchy.
// // This allows you to enable or disable GameObjects instantly without selecting them.
// //
// // Key Features:
// // 1. One-click activation/deactivation directly in Hierarchy.
// // 2. Full Undo/Redo support integrated with Unity's system.
// // 3. Optimized UI placement to avoid overlapping with object names.
// // 4. Visual clarity: Helps quickly identify inactive objects in a complex tree.
// //
// // How to Use:
// // 1. Place this script in an 'Editor' folder.
// // 2. Look at your Hierarchy window; a small checkbox will appear on the far right.
// // 3. Click the checkbox to toggle the Active/Inactive state of any GameObject.
