Webflow is a very good tool, but still in begining.
I miss a lot to style the tags directly. Its not a good practice to associate a class to a tag every time i call it. A link for example. And it shoudnt be dificult to implement.
I passed your post on the whishlist section and I plug in shamelessly.
Styling basic tags could be cool, and we also could be presented a style guide page when we create a new site. On this page, will be placed all the common tags, and we could wtyle them and duplicate them to make variations.
This page could be published or not, could be used to show the style guide to the client. I always build that sort of page, usually in a fake node post, to simulate all the “rich text” possibilities.
