Enable animation selection

Hi! I think it'd be nice if you had, as part of the configuration object, a property for setting the message's animation.

Thanks

Not a bad idea, I'll mark this as a potential enhancement. I welcome anyone who'd like to take a stab at it. Currently there's only one animation (fade) baked in, so it would require a little bit of reworking.
