I had an idea recently and I wanted to share it with the Webflow dev team. When trying to understand how webflow widgets work, for instance g-maps, I see that it works a bit like Web Components. So I guess that if you used something like Polymer, you could add a lot of new features to webflow.
But I don't know what are the limitations of this. I just wanted to share this thought with you and see what you think about it.
