Udemy - Improved Course Library

This extension adds additional course info to the courses in your Udemy library.
It employs the Udemy API to grab more info about the courses in you library and appends the following items to each course:

⁃ The total runtime
⁃ The rating
⁃ The total number of ratings
⁃ The number of students enrolled
⁃ The date of the last update
⁃ Info about available subtitles

Additionally it displays a thin colored strip at the bottom of the course card, from red (3.5 stars and below) to green (5 stars).

That should give you a good overview of which course is worthwhile and which you might want to archive instead.

Note: If a course has stopped enrollment and isn't visible publicly anymore, no stats are available for that course.
