I'm also curious how non-novel this is. Ie if A and B are both pre-existing individually, A+B might still be reasonably novel. Which may be a bad thing honestly. This will do some things where a seasoned designer would avoid for a technical limitation. Ie A and B shouldn't be combined for some logical reason, where as maybe StableDiff would just throw pieces together without care.

But still, StableDiff has been amazing in my view. Prototyping anything this quickly is going to be a game changer. As someone who doesn't think in pictures well, this looks to let me mock things up so incredibly well. I am so hyped for the refinement of the tooling in this space.
