More detail about what it is

It is a HTML page with JavaScript that runs in Firefox and Chrome. It can load course data that can consist of text, pictures and sound.
For example it can "show Chinese character", "wait", "show pinyin", "play sound", "Show English meaning".
All resources (pictures, sounds, texts) used in the questions will be stored locally so after downloading a Lesson or course no connection to the Internet is needed.
Currently only self assessment is supported that means that in the then the user decide if they got it right or wrong. If you got it right the question will not be repeated.
Working on a way to change the steps so you can have it show English first instead of Chinese or wait longer before showing the answer.

Still working on:
Good step editor
Play video step
Other question validators (now the user decides if they got the question right, could have questions that require the user to type text or multiple choice)
Support for Internet Explorer (low priority)
