Hi [*]
I would like to discuss the addition of a possible improvement to the app.
Let's assume a card has only two sides. For more sides, one would need to think it through. But I guess most decks have two sides only.
A great option in this little gem of an app is that one can choose if you want to see side 1 first, or side 2, or even randomized. Now I propose to have a fourth option: Make two completely uncorrelated cards, showing side 1 on one card, and side 2 on the other card. This will effectively double the cards in your deck.
Why would this be a good idea? Well, when I started using FCD for learning a foreign language (FL), I though it's enough to know English --> FL. When I went to the country, I often heard the foreign word, and I knew that I know it, but I did not know what it meant. Similarly, if you tell me a country, I know its capital. If you tell me a capital, I know it's a capital, but I don't know of which country.
Cheers & Thanks for keeping this great app alive!
[*] I leave out the praise for this great app, since I said it before, but this does not mean that my appreciation towards the app has changed in any way.
