I think it will be a good idea to add recyclerview inside a fragment to show multiple currencies, in this case we will cover multiple android topics, we can also cache them with room

That is a showcase to implementing popular library and Google suggested architecture. I don't think to add a new feature, please just open an issue to improve the current implementation.
