I have added a setting that controls the order in sorted word lists. The possible values are:

• Relevance Orders Japanese searches with shorter and more frequent variants at top. (default)
• Frequency Ignores relevance and only uses word usage frequency.
• JLPT - N1 first First results are the words in the JLPT test, with N1 at the top. The rest are sorted by frequency.
• JLPT - N5 first First results are the words in the JLPT test, with N5 at the top. The rest are sorted by frequency.
