Caching what?

Or would it be too slow? Connecting directly to relays is battery intensive, but maybe that can improve

It connects to relays like a client and stores the notes. It acts as a relay you connect to. That way you get the notes from all the relays while only connecting to one. It’s more efficient.

Doesn't citrine do that?

i don't think so, but it could, if it can also connect to a signer with permission to auth for REQs or, since it's local, store your key so it can auth for you to any relays you use that need it. that would cover all cases. #asknostr #citrine does citrine have the ability to act as a relay-proxy?
