When did I last play this cloze?

I’m trying to use the Hard, Normal, and Easy buttons to optimize my recurring reviews. To be able to decide which button to press, it would be beneficial to know when I last played the cloze: if I find it easy after two months (when I pressed Hard) I can probably double the interval (Normal). And if I find something easy after eight months I can probably mark it as permanently mastered. Without this information I have to resort to guesswork, trying to remember my history with the cloze.

The date of last review could go here:
