What I mean is a deep dive on “what good UX is in Polkadot and how to build it” (see The Best UI/UX in the Polkadot Ecosystem and related conversations). Capi, RPCs are both important tools to understand for that. With respect to light clients, the main points to get across are how to maintain good UX while implementing a frontend which uses light clients. The staking dashboard is a good example of a progressive UX that can fall back to a light client but provides a better experience when other services are available.
