Feature Request: Allow changing editor fonts

[DevHyperCoder]

I would like to change the font using the settings screen. I don't have Jetbrains Mono installed on my system and without it, the rendering seems to be wonky.

I changed the font to Fira Code in the tailwind config and now it works properly.

I understand that it might be difficult to detect fonts available when you package it in a AppImage, I'm not sure how complicated it would be.
