@Geek already came up with a note engine like that. That's what I copied. We can show anything. There's no excuse to hide events in daily-driver clients, anymore. He solved that problem very simply and elegantly. Nostr clients can now be future-compliant, as well as backward-compliant. This is especially interesting for threads below OPs. If someone posts something, they want to see everyone who interacted with it, with the standard-kind interactions featured most prominently. In my threads, I reveal stuff like people quoting the event, bookmarking the event, responding to the event with a voice reply, reacting, zapping, highlighting, etc. Some directly on the OP, some behind an accordion at the bottom, and some prominently in the middle. That's why my client feels so "alive" and other clients feel dedder and dedder.
