I absolutely agree, new design is absolutely terrible. Hard to use and understand where the last lesson I left off at.
It's a hard situation, because they clearly are improving the site and adding features to the courses (tracks etc.) that are welcome - perhaps CodeAcademy need to work on communicating what has changed to the users. For example, when I signed up it was really just one exercise after another, now it has tracks/courses/games/lessons. Maybe it is just a wording problem?
We'll also do a better job of fixing wording and explaining what's going on. Thanks again.
