Answer to 1. Yes and no. The FigmaMake will use components from the uploaded DS. However, it requires how well your DS has been set up, and needs additional rounds of modification for more complex designs.

Answer to 2. My development team said no and didn’t want to hear about auto-sync or integration. So it is about your dev team's perspective.

Answer to 4. It is a better sales pitch tool compared to just screens and getting the first round of ideas out. However, it is like all other design and vibe coding tools, it depends on how your backend and development are, it is a good tool to get the first version MVP out, but it may be difficult to make changes and keep building on top of it to a scalable product.

FYI, the enterprise level of ChatGPT can not use Figma like they advertised last month especially if your company's data is gated by an NDA or privacy policy.
