The other day I woke up and read every single nip that is indexed I'm the github (there are a lot of nips but I only read the ones in the "front page") and trust me. Nostr can do a lot of different kinds of things. Basically, when you make a nostr app (with no funds) you can choose to implement a few kinds very well, a bit more kinds good enough, or all of them but none in a usable state. Coracle and amethyst are between class 2 and 3 they can't do everything.
