Switch to hide French (or English) in Saved Vocabulary

I save some vocabulary from each lesson as a succint way to review key phrases/words. It would be very helpful  to have a master toggle  to hide the French (or the English) for all saved vocubulary to test our ability to translate.  Also have a toggle for each saved vocabulary item to uncover the hidden text as needed. I would normally hide the French and test my ability to recall the French phrase/word.  This would accelerate retention.

I found out a custom flashcard set accomplishes this, although it would be easier to not have to create a custom set.  That said, it is a real plus that Rocket French has this capability.
