I don’t understand why the flashcard response icons are arranged in a square, with very similar icons and text which make them difficult to distinguish.
Suggestions:
- Arrange the response icons in a line, so they form a visual continuum / scale from worst recall on the left to best recall on the right.
- Color code the response icons (e.g., red for worst recall, green for best)
- Distinguish the faces better. Currently, two of them (the non-smiling and frowning faces) are nearly identical.
