I have a few suggestions to improve this great application:

1. Allow dictionaries download (trasnlation available offline) - i believe many people will use this application while travelling, which means in most cases won't have internet connection.

2. Allow translation from a previously captured image.

3. Allow for manual image correction before the send for translation - sometimes it says there was no text recognized after taking a photo - especially if the photograph is not black text on white page.

Great work
