I find the black horizontal line for folded blocks distracting. They span my full screen (maybe 100 characters), while my section headers only go to ~70:

what I see

I was wondering if I'm missing some obvious way of formatting these lines, like graying them out or truncating them...?

As you can see in the status bar of the image, I'm using a "user defined language", but I couldn't find any styling options there like this. I also couldn't find anything in Settings > Style Configurator or Preferences. Thanks for any ideas
