Make weeks-old content visible on the homepage so that it can found with a text search

[DavidWhitlock]

A student suggested that an "expand all" button be added so that older content can be visible (and, therefore, searched):

any chance you could add an “expand all” button on the course schedule? When the sections are collapsed, command+F doesn’t work on them, so if I want to reference something and I know a word that was used, but not what week it was in, i have to click through each section

Alternatively, the homepage could still display the content from the entire course, but it could be organized better to make the upcoming content more visible. So, maybe:

• Coming next (in the next week)
• Recently on (in the prior week)
• Later on (in the following weeks)
• Previously on (everything more than a week old)
