3.2 Beta was released, please go to the download page to get one. In this new version, Layouts and courses of single-handed Dvorak keyboards were added. The contents of the courses were improved. The program has more fault tolerance for the course files generated by the third parties. The help files for defining a virtual keyboard layout and generating a typing course were more detailed.
Beta is full functional and stable.
You comments on this single-handed course are greatly welcome, and I would appreciate contacts and cooperation from any organization helping people with disabilities. The default password for advanced functions is love. A small program named Hypnotist for people with a bit insomnia. If you or your friends have a bit insomnia, please get this utility to have a try.
