Hide English Sentences (WaniKani)

Hides the english translation of sentences until a button is clicked.

On the WaniKani.com website, by default the English translation for sentences is shown below the Japanese. The proximity of the translation made it tougher to attempt to translate the Japanese on my own. This extension adds a button to toggle the visibility of the English sentence, allowing users to rely on their own abilities without the possibility of reading the English.
