Current problem: In DuoCards the cards always go through the same cycle, which makes learning predictable and less effective.
Suggestion:
Introduce a mode where cards are randomly shuffled after each round or even change sides (e.g. with English to Russian translation).
Benefits:
* Improves memorization: Randomly arranging the cards makes the brain work harder, rather than just "memorizing" them in a certain order.
* Increases interest: Unpredictability makes learning more exciting and keeps you from getting bored.
* Best Practice: Corresponds to real-life speech contexts where words appear in random order.
