Fixed width prevents jitter or movement when toggling between "ON" and "OFF".

inline-flex layout ensures it aligns naturally with YouTube's + Create button.

Smooth transitions with hover effect.

🧠 Replaced setInterval with MutationObserver: Dynamically watches the DOM for changes, improving performance and reducing CPU usage.

🔁 Added queue system: Limits concurrent API requests (max 3), avoiding request overload and potential rate-limiting.

⚠️ Implemented retry mechanism: Automatically retries failed fetches up to 3 times with backoff delay.

🧹 Memory-safe processing: Automatically cleans up stale processed entries older than 10 minutes.

📅 Added UI toggle button: Fixed-position toggle to enable or disable the script in real time without refreshing the page.

🔒 Improved video ID extraction: More accurate detection of video IDs from all types of YouTube URLs.

🧼 Cleaner and modular codebase: Easier to maintain and extend in the future.

YouTube Date Format Script: Improvements and Changes

Overview

The "Full Date format for YouTube" userscript has been updated to address several issues that were causing it to fail with YouTube's current layout. This document explains the changes made and how they improve script functionality.

Major Improvements

1. Enhanced Video ID Extraction

What changed: Added support for more URL formats, better fragment handling, and error handling to prevent script crashes if a URL is in an unexpected format.

2. Improved DOM Element Selection

What changed: Completely reworked selectors to match YouTube's current DOM structure and organized them into a more maintainable format.

3. Robust Metadata Date Insertion

What changed: Instead of blindly targeting the second span, the script now intelligently finds the best place to insert the date by looking for view count elements.

4. Comprehensive Debugging System

What changed: Added a debugging system that can be toggled on to help diagnose issues without cluttering the console during normal operation.

5. Better Page Navigation Handling

What changed: Added more reliable URL change detection to properly handle YouTube's single-page application navigation.

6. Improved Date Formatting

What changed: Added validation to check if the date is valid before proceeding, and wrapped the function in a try-catch to prevent script crashes.

7. Multiple Processing Attempts

What changed: Added multiple processing attempts at different times to catch elements as they load asynchronously.

Other Enhancements

1. Error Handling: Added try-catch blocks in critical functions to prevent script crashes.
2. Visual Styling: Added spacing to the date display (holder.style.marginLeft = '4px').
3. Cleaner Code Organization: Restructured code for better maintainability.
4. Performance Optimization: Improved caching and prevented unnecessary reprocessing.
5. Memory Management: Maintained cleanup of old cache entries to prevent memory leaks.
