Let me thank you for creating such a well-crafted package. โคโคโค
I wanted to create a customized version of the DeckAnimation and one of the requirements is to change the count of visible cards. Based on the source code, I need to change LayoutConfig.cardsBefore to a different value, let's say 4, but as this type isn't in the list of exposed types, I couldn't override the layoutConfig property to return a different LayoutConfig instance. This is the same for the AnimationConfig type.
