I mentioned this here talking with Ulco: https://planetside.co.uk/forums/index.php/topic,27470.msg272897.html#new
But it would be cool to have a setting in cards to make them "quasi-3d" that is, that they always face the camera (without having to setup and track the camera manually). That way we could do multiple viewing angles for certain elements without a dozen cards. Like candle flames, just like in game engines.
Maybe two settings, rotation, and rail. Rotation meaning the card simply rotates to face the camera, and rail, it translates and rotates in a circle (based on card size), facing the camera.
