It would be really cool if we can get the romaji with the context sentences ,It should be hidden by default and the user can check the pronunciation after reading the context sentence to avoid mispronunciation.
This can be useful as there are multiple readings and the user can make sure that he is using the correct reading
Update:Belathazar’s comment made me realize that furigana would be better
You really ought to be weaning yourself off romaji as quickly as you can manage.
Furigana, on the other hand, though. I’m pretty sure you can find browser extensions that’ll add furigana. Or at least tell you the reading of words you highlight or somesuch.
