Today's small update adds a Repeat button to the Review Summary page, for the Free Review mode. Thanks to Necrojesta for the suggestion.

An interesting effect with repeat reviews using the Example On/Kun Readings option, is that you may see different example words for the same character, on successive reviews. This is because the example words are selected at random from priority entries in the dictionary. Kanji which are more common may show different example words on successive reviews.
