- Added functionality for managing the overworld map, including loading, rendering, and saving map data for both Light and Dark Worlds. - Introduced new canvas components for overworld map editing, allowing users to select and paint tiles directly onto the map. - Enhanced the ScreenEditor with controls for tile flipping and palette selection, improving the user interface for overworld map management. Benefits: - Expands the capabilities of the ScreenEditor, providing users with tools to edit and manage the overworld map effectively. - Improves user experience by enabling intuitive tile editing and visual feedback during map modifications.
