also, things like default URLs --> seems like this would start adding more complexity than necessary. I prefer the class based approach because we don't know what kind of tiles we'd want in the future, and this keeps things more flexible. Adding another layer on top of that just seems...gross. Especially when you still have to think about user-facing text! That still has to go somewhere. Here it's at least contained.
