This is cool and solves some of the issues around staying organized when creating a final polish punchlist that come up, even when I'm doing the design and dev myself :-).

Couple thoughts -

When adding a new comment, I was surprised that mine became "1" which reflowed all the numbers. Seems like it would be helpful to append the comments so that the numbers stayed static.

Also, it would be neat if I could change the styles of all the similar elements at the same time. For example, when editing the .storylink class, it would be neat if I could choose to edit all similar elements or just that specific instance (like I can in the normal inspector). That would make it easier to preview my changes and make what I am trying to change clearer to the developer.

Another feature this brought to mind would be a way to preview all the colors in use on the page, kind of reverse engineering SCSS color variables. That way a designer could preview what changing orange --> green across all uses might look like before committing to it. The designer could also suggest a new color be added to the palette. In a dream world, this would also work for all font styles in use. Basically creating a reverse style sheet so you could see and consolidate minor differences. Maybe this is what you mean by style and component linting?

Finally, it would be cool to have "versions" or "groups" of the edits. We often debate whether we should go one direction or another, and being able to flip between a few options without fully coding a solution would be neat.

Cool project and good work!
