How to change the default font family?

[Qiuyi-Hong]

Hello , I found this plugin really useful. However, I have noticed that the console cell still uses default font as well as the advanced setting pages. I am wondering is there a way to use this plugin to customize the default font family (which is Menlo for mac) for all the monospaced font?
Thanks

I wish i could set font Monospace in markdown cell as well !
