The font size of the arrow labels is the same as that of the card text and note text. That is not only distracting but is not correct because the arrow label is less important than the content of cards.
Also, some labels are more important.
The ability to use a different font size and color.
None
Bumping this, the label font size seems to be relative to the zoom level making it awkward to arrange notes sometimes.
A work around I have discovered is adding custom css to obsidian. You can modify the css class canvas-path-label to have a set font size.
Can you provide detailed instruction? What exactly should I add to obsidian.css and to what section in it?
add a css snippet
.canvas-path-label{font-size: (px number you want)px}
