Further help with line spacing in Edit Mode

Okay I found this thread: How to make list indents deeper in editor mode?

from which I derived this code:

.cm-s-obsidian pre.HyperMD-list-line {
  padding-bottom: 0px !important;
}

So it seems that fixes my problems with lists.

If I can just figure out headings I will have advanced all the way to zero LOL.
