How to learn using Flip Cards

Flip Card learning has been requested a lot on here, and i think it’s very useful for some of us. It allows self-cheating, but speeds up the speed of repeating words a lot.

I therefore created a userscript to allow me to use flip-cards. It’s still extremly ugly and buggy, but in some cases it works as intended.

Feel free to test it, and please submit some feedback.
