About
You find the global purpose settings for Designer in Site administration > Plugins > Course formats > Designer Format > General settings and then in the tab Purpose.
If in the course format settings the course type "Normal" and the course layout "Show one section per page" is selected, the sections on the main course page display icons for each activity. Instead of using a different icon for every activity type, you can group them under a common purpose.
Available settings
The list shows all activities available in your Moodle installation. For each activity you can select a purpose from the dropdown menu. The available purposes are:
Administration
Assessment
Collaboration
Communication
Content
Other
Interactive content
Note: Each purpose and its icon can be managed globally.
Tip: Assign activities you want to hide to the "Other" purpose and then disable that purpose in the global management settings.
