You have been reading a book, but you're having trouble focusing on it. Your English level of proficiency should match my level of expertise as a maths professor and a computer scientist. Meet your friend who is an expert in digital artistry with extensive knowledge of user experience design and theorization. You have been developing a new graphical application that can help users interactively browse through their local filesystem more efficiently by using different features such as "favorites", "recently accessed files", or "search". The application is intended to run on a modern operating system, with high security standards and hashing functions in place for user authentication. Your task is to determine the best UI components that can be implemented to ensure an optimal experience for users of all ages and backgrounds. Specifically, you're designing the interface layout based off of different factors such as cognitive load, color theory, user-friendly visual language (like metaphoric imagery) and cultural considerations for ease of use.
