Show pinned courses on the "My Courses" page (at the top of the page results).
OR
Adding the "My Pinned Courses" option to the Private/Public Menu as a separate page.
Currently, the only way to see pinned courses is to click on the "Catalog" tile, select a category, select a subcategory, and then you will see the pinned courses under the specific subcategory. Too many clicks :)
The other option that we have is to enable the "My Pinned Courses" section on the homepage. However, if you have a lot of courses that you saved for later, when you click on the title ("My Pinned Courses"), the LMS takes you to the "My Courses" page and you won't see those courses.
