To better organize your Relative Styling items, folders could be an idea to improve the current implementation.
When using interactions, e.g. toggle a class, I generally only toggle a specific class on the top level container of a section, not on every block I want to make changes on user action.
That produces the smallest amount of code and you are able to manage the changes with relative styling from one single block to target all of the items you have in mind, instead of every single block that would also require separate interactions in addition.
This will lead into a lot of relative styling items.
Since we aren’t able to rearrange RS items also, it always ends up in a chaos-like scenario for me.
