First, your plugin is awesome, and totally a core, essential feature for wordpress. I can't imaging running wordpress without this functionality.
I'd really like to see something in the URL admin area that enabled wildcard characters or some kind of logic that would ease the burden of entering language specific URLs.
I have a URL like this http://www.domain.com/some/path/to-page
and I'd like to enter something like this in the URL admin
Can you consider doing this? I must not be the only person running multilingual sites and using Plugin Organizer. Anyone else?
