More font options

1. Describe the feature request

An option to set different fonts from the system preferences is greatly appreciated. A way to install or upload a font would be even better.

Changing the monospace font is also necessary.

I hope you are able to get to this as I can also see a plethora of other issues as well ❤️‍🩹

Ability to change the font sizes consistently across the app would be great. It doesn't seem like we can change font sizes in the flow page.
