I know someone has mentioned this earlier, but I want to bring it back to your attention.
Please could you show the course title and the lesson title in two different lines? There seems to be enough place in the rectangle where you show the lessons. Often the course titles have about 15 to 20 characters, and then there are only 2 or 3 words of the lesson title shown which is often much to short to see what the lesson is about. In older versions of LingQ you have shown more of the titles.
