Hello! How can one define or set a theme in which the default background color and individual email styles are toggled to a more reable, less cluttered look? Many other email clients allow for themes in which the background color and foreground color of text can be set. Wouldnt it be nice to have a button, that toggles between: - Default theme with individual email following their own styles - Custom set easy to read Thunderbird message View window background color, Messages index background color, Text foreground color. Is this something that can be set in the configuration or that can be hacked into Thunderbird? I dont like the dark theme, its too dark and gives me eyestrain I dont like the white theme, its too white and gives me eyestrain The theme pack from Postbox are excellent examples of how people want to read emails in 2022! https://support.postbox-inc.com/hc/article_attachments/360097923194/pb7-screenshot-home-themes-3-short_2x.png Where can I sign up to help as a designer?
