Disable-switch for display of translations on the default front page node

Instead of displaying all translations on the front page, it would be nice to be able to chose to only display the standard language. When chosing a different language from the menu, then only this language would be displayed.
Right now Drupal even displays all versions after having chosen a language. That doesn't seem to be of much use. If a visitor clicks on french, only the french versions should be displayed (or standard language only of an article if no french version is available).
