Moodle users have the option of creating a filtered course list to show a condensed list of current courses and replace the 'Course overview' block.
shortname | exp | My courses | (FA17) to
shortname | exp | Fall 2020 | (FA20) (in future semesters, use the abbreviation for the current semester)
Optional: Add a second line of code that reads
shortname | collapsed | Upcoming | (SP21) to show your courses for the upcoming semester, but collapsed under a toggle.
You can now safely delete the 'Course overview' block.
