So many improvement in 7.1 but it look like it will be still the same situation for Multi language sites.
At the moment, it is almost impossible to have an efficient Multi language site, as it is just possible to translate the system, but not display content in a selected language.
So my idea/dream is:
Give the choice to the author/admin of showing the content for each language.
For example when writing an article , or an event,.... to have something like:
Show this article in:
1. All language
2. English
3. French
....
and have the box in index / Events home,.... just showing the content from the selected language
