We've been utilizing Sketch libraries to create wireframe components and flow diagrams. These documents are created within a large artboard as we pull in other artboard symbols of the actual screen designs and link them together. We annotate directly onto the large artboard when we need to clarify the transition or interactions happening. https://useflowkit.com/ We use this library to link screens together and its been super useful.
