It's awesome to see how much progress you've made on this, and happy I was able to help out! :)
I still have a few major features to add: I'm currently adding commands to move books and pages around, and I'd also like to add a simple way to import/export source text. And a backup system that doesn't suck. And... well, you get the idea :) On the other hand, I'm definitely looking forward to work again on Phalanstery. I guess I'll do both!
