An option to configure minimum font size, or other custom CSS to override the html styling in the mail would also be very welcome on my end. I understand that for some the ability to express ones character or message via html is important (e.g. emojis and tables are important for me) but having a way to overwrite certain options for readability is probably an important accessibility feature as well. Similar to having a way to zoom in.
I have no idea if that is feasible at all but having an extension like Stylish or Darkreader run in the electron framework would be awesome
Aside: I tried to modify the font size quick and dirty via a theme and although I import email-frame I cannot seem to find a way to overwrite the value in my theme. However, CSS and LESS are still very much foreign languages to me and I don’t know what class/id to target. So documentation on how to customize the Email body style would be very welcomed.
