Are there any tools that leverage vision for UI development? Use case: I am working on a hobby project that uses TS/React as frontend. I can use local or cloud LLMs in VSCode but even those with vision require that I take a screenshot and paste it to a chat. Ideally, I would want it all automated until some stop criterion is met (even if only n-iterations). But even an extension that would screenshot a preview and paste it to chat (triggered by a keyboard shortcut) would be a big time-saver.
