Color in UI automation editor

I know a lot of people use the yaml directly for building an automation.
but personally I almost always begin with the UI and add the detail later, that way I don’t have the mind most of the code.
but if you use more then 2 imbrication with the UI you found yourself with something like that:

this is just a part of this automation (it’s a birth pill reminder)
and you cannot always make out where you are in it.
first choose, second, in the loop?

so I suggest to add color to the panel to see more contrast and at what stage you are.
something like that (pardon my paint skill):

I hope my drawing was enough for you to understand :stuck_out_tongue:

This would definitely improve usability for the more complex automations!

Can this be done with themes? On https://www.home-assistant.io/integrations/frontend/#defining-themes there is mention of ha-style.ts. I tried including some of these (those with ‘border’ in the variable name) into my configuration.yaml and applied the theme to my profile, but I did not get the desired effect…

Is there someone with more experience/knowledge out there?
