ACK. I would like it the way it was done on the EU website until some time ago: On a page with multiple language versions (up to 20 or something …) they showed circles with the ISO language code in it, on which you could click.
I would like to be able to set a default language (or an ordered list) in my preferences, if none of the user’s Content-Negotiation languages is matching, and use those if available and matching.
Why I’d like this feature: I’m currently learning Italian and I’d like to translate some weblog entries to Italian for practice. And no, categories cannot replace language management. Especially, <rel /> links to other language versions and appropriate meta data have to be created.
