It's kinda shocking how poorly the ux for slack scales when you're in lots of threads/channels. The fact that cmd+k isn't frecency-based is mind boggling. There's the back/fwd buttons, but they aren't jumpable.

Tonight, @rawkode.dev will be joined by @jimmy.zelinskie.com of @authzed.com to get hands-on and show you how to adopt SpiceDB; an Open Source, Google Zanzibar-inspired database for scalably storing and querying fine-grained authorization data. AuthZ has never been so good. Let's have some fun!
