Alex there is no "automatic" way of implementing a design yet. You'll have to reproduce any designs from Figma into Webflow. Our component library will get you about 75% there though - maybe more - it just depends on how many changes you've made in Figma.
No, Emily said that you can use that plugin to sync variables but that plugin was built by webflow not us. And the code that the plugin generates does not follow client-first - thus my original answer. Hope that clarifies it.
