Engine tab - "Engine" is a technical term that is not really helpful here. How about "Languages" instead ? - There are some icons missing in the combo box, e.g Telugu-apple, Telugu-rts, Marathi-phonetic, Marathi-itrans... - The main list needs to repeat the language name (like the status icon menu already does) otherwise it is not clear if "phonetic" is Oriya or Marathi.
Fixed in upstream. Wait for next release.
