Here's how to navigate a course page in Moodle's Boost theme.
- Turn editing on and take care of other administrative tasks by opening the administration gear in the upper right corner.
- Scroll to the bottom of the options list and click on More if you don't see a link for a particular function.
- Create more working space on your page by clicking on the "hamburger" icon in the upper left corner to collapse the left column. Click on it again to expand your page and access the course links in the left column.
When you open the More link, you'll find a page with two tabs: Course administration and Users. Each tab has links to functions that we're used to seeing in left blocks.
The Course administration tab has all of the standard course administration links plus links related to reports, badges, and question banks. Note especially the Recycle bin (new in 3.1), Dates, and Course completion links.
