Slot.gd
Learn about the Slot node, what it does, and why it's needed.
What is a Slot?
A slot is a node placed in a +layout.tscn used as a placeholder for pages or nested layouts. This effectively tells where a page should go to preserve its location in the scene tree.
It uses a custom class to allow adding to the scene directly and offers a @tool script to provide possible error messages.
