When can you create a new layout or modify an existing one?
You can create a new layout or modify an existing one when you have the appropriate permissions or access rights in the design or development environment. Typically, this is done during the planning phase of a project, or when updates are needed based on user feedback or changing requirements. It's important to ensure that any changes maintain consistency with the overall design guidelines and user experience objectives. Additionally, modifying layouts should be done carefully to avoid disrupting existing functionality.
