I have no idea how to pronounce any of the names, so some kind of link from the written name to an audio clip would be useful.
Also, it'd be nice to have some "translator's notes". Perhaps there's some nice phrases in the original that just don't translate well; or some idiom that doesn't have an exact English version.
Sure I can just use a computer and browser and a search engine, but it'd be nicer if it was built in.
