As a darkmode user, it's great when replying to a55holes who try to blind me by hard-coding the background color as white using CSS.
But now using this plugin I've become part of the problem.
* {
color: #ccc !important;
background-color: #000 !important;
}
Ideally I'd like to have a regex search for styles applied in the email, and only apply my "no, actually FU" styles if they did it first. That way the 99% of civilized people who do not set styles globally on background-color or color will not be impacted and can have any email text show up automatically on their side in their preferred default colors, and on my side with my preferred colors.

Just what I needed to customize the quotes so that they would display correctly for recipients using Outlook or Gmail.

Thanks, getting quoted text formatted "right" was the exact use case which impelled me to write it. :)

Thanks for the extension, it works :D
There are two features that would be awesome
a) Ability to have different CSS depending on the email account
b) Ability to use a css file (similar to signatures) as optional to the built-in editor

Excellent extension.
You can set a default email template with all the advantages of the css.

A good and simple way to keep the style consistent in all the outgoing email, new and replies alike. Thank you!
