Nice work. Quick look at your repo and I'm impressed with how you indented your work. Its makes everything readable (most of the javascript I've seen is a mess, maybe I read too much bad code)

Offline access would be an awesome feature, especially for users who are not "always connected".

congratulations, this looks very nice! some wishes after playing with it a little: - keyboard control over the interface! - an option to mark an info as learned - import option
