This project was never intended to help anyone learn QF/n. That's what the official examples are for.
This project was an experiment. It is not a good example of a QF/n app.
I once wrote about this project:
You are spending your effort trying to understand my terrible UI implementation that uses a paradigm I barely understood and written in a UI framework (WPF) which MS doesn't seem to care about anymore.
