jrNova skin - Language function
Design and Skin Customization
It's not something that is going to be coming really soon, but long term I want to set language's up so they can be shared and loaded directly from within the ACP - i.e. you'd go to your language tab for a module and you'd only have en-US installed (for example) - you'd click on "get more languages" and you would see a list of translations for that module that have been "shared" by other JR site owners. One click and it would setup in your site as well. You could also choose to share your own custom translation.
I think that would be really cool
