That’s cool! How did you build it, just have an agent have a go at it?
We do have a public demo component available: GitHub - discourse/discourse-discovery-sidebar: Demo component for discovery-sidebar blocks · GitHub
Right now that’s just what we use here on Meta as well, as we wanted to focus on a generic foundation in this initial step. Though as said, I think there’s many useful and fun features we can surface with more custom panels.
