@BenWhately has explained, in a meeting, that they didn’t want to make community-created courses searchable in their Apps. I have an alternative idea that is easier to implement: Remind the user to go for community-created courses after finishing the last official course.
For example, at the bottom of Spanish 1, users see the link to Spanish 2.
The last official Spanish course is Spanish 7, the link to which is available at the bottom to Spanish 6. At the bottom of Spanish 7, however, there’s nothing.
My request is to include a text at the bottom that suggests the user to go for a community-created course on the web version to continue their study.
