nostr:npub1v0lxxxxutpvrelsksy8cdhgfux9l6a42hsj2qzquu2zk7vc9qnkszrqj49 how are the category tags determined at the top of zap.stream?

Would love to see a "development" or "Programming" category. When I try to type in one of those to stream, it gives my a dropdown with seemingly on related stuff. Maybe Im doing something wrong. lol
