I wish Joomla! would handle translation in the same way Zoolingual does it. Translating items into different languages is - once setup correctly - really userfriendly for editors. The translation for all languages is done within each item. Perhaps some autoclosed panels would be useful in sites that have many different languages.
Eventhough it does take some time to figure out how to set it up, once that's done, it's a really useful and easy to use tool.
