While I don't think the rich text thing is particularly useful, I'm very impressed by the approach, especially how it manages to change the resulting image in a way you can control (that is, without regenerating the whole thing and ending up with something with random undesirable changes). The stability of the overall image during local changes makes me think that maybe this could be a key to video generation (because the biggest problem with existing diffusion-based approach for video is their instability from frame to frame).
