I think you'll need to modify the overlay view to add a text binding and also modify the controller to get the dictionary items. I haven't used dictionary values, so not sure if it can be done with a directive in the view rather than changing core javascript, which is rarely a good idea. ;)

That said, the template/html is probably inlined in the javascript anyway... If you're ok with making upgrades a little bit painful, changing the javascript isn't entirely bad.

I've hidden plenty of stuff, but that's a whole lot easier than adding...
