How about support for RTL languages/books? There are a number of typing practice sites that allow you to use custom texts, but I haven't seen any that work well with RTL. A dream feature would be to be able to upload RTL epub files and type away! This is the most beautiful and pleasant typing practice experience I've ever had.
