For six years now, I've worked on a package that helps frontenders document components visually, or to highlight elements. I haven't got any wide scale (or any scale) usage on it, but would love for devs to at least check it out, to see if it is a viable thing, and if that it can be used as intended. I've had it in use for a clients design system documentation for several years, but they have now opted out of it. Feel free to provide feedback, would love to hear from you :)
