Nice client. First I've seen it. I hope it surpasses gossip so I can retire.
nostr:npub1syjmjy0dp62dhccq3g97fr87tngvpvzey08llyt6ul58m2zqpzps9wf6wl is it time for you to set-up NIP-17 DMs for yourself? (Don't worry, this isn't a Jumble feature request).
If you think it is then I recommend https://github.com/lumehq/coop (compile from source).
