Warning & Suggestion code instead of solely verbal feedback

[dominguesgm]

In order to work well with localized web pages/apps, one must currently map the written feedback to their translations.

For this library to provide a better experience for developing in different locales, I think it would be a good idea to add feedback.suggestion_code and feedback.warning_code which could be simpler, more concise and less prone to change which would break translations.

For example, Add another word or two. Uncommon words are better could have code add_words or Avoid repeated words and characters could have code avoid_repeated.

This would be a less prone to failure way to enable mapping custom feedback.

This project is unmaintained by Dropbox for a long time now.

There is an active fork with i18n support. See #290 (comment).
