In the old UI, you could select Share in the dropdown menu for a media tile in the Library, and then click the Class tab to immediately share a video with a class.
In the new UI, the Class tab has been removed from the Share dialog. Now users must first view a video, wait for the new page to load, then click on the Publishing tab, and then click on the Classes sub-tab in order to share a video with a class.
Please add the shortcut back!
