Here's a few updates I think need to/should be done to the Word Bank,
1) Multiple word banks
2) Ability to add an entire "series" of vocabulary. Right now, you need to add the entire lesson, which can be cumbersome if you're trying to review the entire series/season.
3) Move kana entries from hiragana to katakana (for loan words)
4) Add a history for successfully recognizing a word, kanji, voice entry, etc,. (e.g., a success rate with number of times recognized/not recognized).
5) Make Word Bank sortable (for kana, romaji, English)
Fixes
1) Really should do a check for testing words back-to-back.
