Looks really nice, but I noticed it's taken away my favourite feature! Before I could click on a particular topic and practice it, but now I can only re-do a particular lesson. It just says "Strength Full" where it used to give me the option to do some more questions - sadly I know I need practice!

Fortunately this feature is still on the main website - it's my main way of trying to consolidate what I learned the previous day.
