I very much like the no LLM output in communication. Nothing is worse than getting huge body of text the sender clearly hasn't even read. Then you either have to ignore it or spend 15 minutes explaining why their text isn't even relevant to the conversation.

Sort of related, Plex doesn't have a desktop music app, and the PlexAmp iOS app is good but meh. So I spent the weekend vibe coding my own Plex music apps (macOS and iOs), and I have been absolutely blown away at what I was able to make. I'm sure code quality is terrible, and I'm not sure if a human would be able to jump in there and do anything, but they are already the apps I'm using day-to-day for music.
