When opening a course on the web, the user is presented with a Difficult Words, a Listening, a Speed Review and a Review button (I believe if there are still new words also a ‘Learn’ button):
Request: Make the Speed Review, Difficult Words and Listening button available on at the level itself. Same look as this as when the user views a whole course (above).
As the image shows: there are no buttons for Speed Review or Difficult Words. These functions are also not available in the Options menu (normal Review and Preview are there, which is good).
Advantage: feature allows the user to do Speed Review or work on Difficult Words for one level only. In the (Android) App this is already possible.
