Only English/Chinese/Japanese are available.
No simplified Chinese, and no romanization, phonetics or transliteration. The addon is not for non Asian who want to learn Asian languages.
I would like more features please, and more European (or other) languages, like French, etc...
You included in the description how to add more languages, but too time-consuming and complicated, please make it more user-friendly. I cannot find where the Service API option is in the option page, anyway, it should be more simple to add languages, please, fix this.
