 1. The auto-suggestion words are derived from Google's [1/3 million most frequent English words](http://norvig.com/ngrams/count_1w.txt). I have refined this list to 140,402 words, removing nearly all misspelled ones. Candidate words are sorted by frequency.
 2. HallelujahIM also functions as a Spell-Checker: when you input an incorrect word, it will suggest the right alternatives.
-3. HallelujahIM also serves as a Text Expander: it loads the file `~/.you_expand_me.json` from your Home directory. Here, you can define your favorite substitutions, such as `{"te":"text expander", "yem":"you expand me"}`.

 4. Instant translation is available as you type words (currently, it only supports English-to-Chinese, but the translation dictionary can be configured later on).
 5. Pinyin to English: you can input Hanyu Pinyin and receive the matching English word.
 6. Fuzzy phonetic match is another feature. For example, you can input `cerrage` or `kerrage` to get `courage`, and `aosome` or `ausome` to get `awesome`.
