I was wondering how I can add a gray box when reviewing that shows a hint. For example if you are testing あの> English the answer could be “that or um” . I mentioned this in the Genki deck and it was implemented, but i am not sure how to add this to my own decks. When I think about all the synonyms going from English > Japanese it would be useful to have a gray box that states ( not —).Like in my screen shot here from the Genki deck.
I imagine this is done by scripts? Could anyone let me know how I could do this? Thank you. I suppose an alternative is just to add another synonym as an accepted entry.
