When going through new posts, it would be immensely helpful, if we knew what lesson or - as a minimum - what course the post relates to.
Please make the course tags verbose? 01_abc_xy is fine for a database, but less digestable for human brains.
An added bonus would be if the tag would link to the lesson (or if you don’t own the course, then linked to the course), but that isn’t quite as high a priority as knowing the name of the course and lesson.
Thank you for reading ^^
