Inline image rendering, media upload/download and previews, profile pictures, reactions, message deletion, reply previews, NSec export, logout, follow-checks, view user profiles, create groups with members.
All done by directly using the White Noise CLI.
BTW you can point your agents to https://github.com/marmot-protocol/whitenoise-rs/tree/master/src/cli and tell them to try out the White Noise CLI. It works surprisingly well.
