While studying the theory of design thinking and user experience, I really wanted to create a design that reflected one simple idea: the interface of an entire app (even the deepest one) could be contained within the frame of a single screen or scene. This is experimental work and I haven't had any research.
After the failure of this project. It made me realize how many hours I had wasted on something that turned out to be unnecessary. It taught me to be regularly aware of the ratio of the effectiveness of a task to the amount of time spent on it. 😐
