Can I change the config to provide immediate focus on current document?

I’m a new Obsidian user. I’m mostly on Windows, but will be using it more on macOS over time. The biggest annoyance for me is the following:

  • When a new note is created it doesn’t have focus (that’s a bug I can live with)
  • I end up clicking around multiple times to get focus on my large monitor because there is a border/margin on the editor per the screenshot.

Is there a way that I can change the colour of the margin’s around the editor so that I can clearly see where the editor is? I think that’d help me a lot right now as I trust the developers to come up with the best solutions over time.
