Thank you for the ActionMailer previews. Working on an app with a bunch of mailers - things get wily fast, and a bunch of static files sit around to be tested for display.

I think the secrets.yml idea, while in development, is awesome and helpful for organization. However, I'd be a little concerned that a single file has everything secret-y in it. Maybe that's paranoia though. It'd be nice if this wasn't just a config thing that I could hand roll myself, and instead offered some sort of obscuration/security measure in and of itself.
