Next up is cardbox quizzes, followed by cardbox sync. I'm very excited to get this implemented. I was doing some quizzes on my phone this morning (because I can!) and wishing I could use the app to interface with the cardbox system on my laptop. Once it can, this is going to be a wicked cool app.
I've been going back and forth about how I might implement cardbox sync. I think I'm leaning toward integrating with Dropbox. The service is free, they have an API that should be pretty easy to talk to, and I know some Zyzzyva users who are already using it to keep their quiz data in sync between computers. I hope it will turn out to be a brilliant and easy solution, at least for now. I'll find out soon enough whether that's true.
Here are some screenshots. Is it not nifty?
