Filter languages
Some of the content users put in Ideascube is not related to a specific language, for example pictures, music-only media, etc...
To address this fact, we added a new value in the drop-down lists where users normally choose the language of a content: "suitable for all languages". In this way, users can mark content as being suitable for all languages, instead of being in a specific language. (!807 (merged))
One question still left to answer is about content filtering.
Users can list content, and filter it by language.
When they say "give me the English content", should we give them only the content in English? Or should we instead assume that what they really want is "the content I can understand" and they happen to understand English?
The latter implies that when a user requests the English content, we should return both the content in English as well as the content that is suitable for all languages.
We're leaning towards the latter strongly at this point, but that's not implemented yet.
