Leitner cardfile system. You can't type in the answer to a question, but are asked if you knew it. Time limit is available in training mode. Prints in paper card format. Flashcards invertible in training mode.
Switches keyboard layout automatically with flashcard side user is going to input.
A neat application that keeps its promises. Some more key shortcuts would be nice, anyway. Tetris-like spelling game, no flashcard trainer. Simply sets up lists of words to translate. You can mark words as known in order to skip them forever.
