futures is definitely the big one for me. Getting all concurrency fully on async/awaits is amazing, e.g. actix-web awaiting an endpoint calling juniper for graphql, with async resolver methods making async calls against my DB, without needing to spawn a single thread, is lovely. Still doesn't work as smoothly as that, even though on paper it ought to. Getting close though.
