Kudos to @cspags for bringing this Modkit for Webflow Chrome extension. For the time being, it allows only an option to move the breadcrumb navigation bar to the top of the designer and the ability to maximize the code editor in the designer. Let’s hope more features would be added to it (e.g. have the Navigator on the right panel as before) .
PS: I am announcing this in the forum, since it was posted on Facebook only. I think it is a grand mistake to have several community platforms instead of one. More here.
