Here is an idea. We can import Figma to Plasmic. What about allowing importing HTML to Plasmic? There is this plugin that imports HTML to Figma. I imagine one could convert HTML to Figma, and then convert the Figma to Plasmic.
It would be nice if in one step I could just take existing HTML and generate Plasmic layers from it. It would help with the adoption of Plasmic if I can easily import my existing HTML.
