Hi! I'm the author. I should remove that "pre-release" notice. Sure; there's plenty more that I could talk about, but there's also plenty of stuff there that you can use right now (and most of the stuff I wanted to talk about). Suggestions come in faster than I have time to implement them, so... Maybe this will never be done, and maybe that doesn't stop it from being a useful resource :-) I hope you enjoy it!
