Would it be possible to add this as a core setting?
It looks like there may already be a theme component that does this, per your other topic - How to show Category Hierarchy in Topic-List with CSS - #2 by Moin
If that solves it for you, am I good to close off this feature request to avoid doubling up?

yes, thanks. It actually solved with the problem.
Maybe that´s still something for the “Standard” settings. If not, the theme-component solved my Problem perfectly. Thanks again

I’ve tweaked the OP to better reflect the updated feature request, but please feel free to flesh it out and make a stronger case for it if you’d like to.
