## Description

The "Udemy - Improved Course Library" Chrome extension enriches your Udemy course library by displaying detailed information for each course. It fetches data directly from the Udemy API to show key insights such as total runtime, overall rating, number of ratings, enrolled students, last update date, and available subtitles.

Additionally, it visually highlights each course with a colored strip indicating quality (from red for lower ratings to green for top-rated courses). This helps users quickly identify valuable courses and decide which to prioritize or archive. The extension is open-source and not officially affiliated with Udemy, providing an independent enhancement to your learning management experience.
