Adding more colors and font choices would be nice. A full RGB/Hex color picker should be reasonable. Also, as an avid Google Fonts user, I would appreciate the addition of Google Fonts. I use Proton Mail as my professional email, and adding colors and fonts can really help with consistent branding. I understand the limitations with displaying non-standard fonts in emails, but I would think colors should be pretty easy.

It is very important for the satisfaction of use to create and feature more customizing options as named.

I wholeheartedly approve this request because I too am bitterly disappointed in the lack of customization features to make my Proton mailbox MY style, especially writing my e-mails should satisfy my needs and my moods instead of imposing such a tight choice of fonts and colors, there is not even my favorite color which so happens to be also Proton's favorite color which is purple nor my favorite font which so happens to be also the CERN's favorite font which is Comic Sans, how am I supposed to feel at home if I can't even write my mails with my favorite font and color which so happen to be also Proton's favorite font and color that they didn't include into their mailboxes for some reasons?!
I think Proton Mail should include at least the most known fonts from each of the Vox-ATypI classification's 11 fonts families in order to satisfy every user's needs and moods such as:
- Centaur
- Garamond
- Times New Roman
- Georgia
- Bodoni
- Didot
- Clarendon
- Rockwell
- Gill Sans
- Futura
- Helvetica
- Arial
- Verdana
- Optima
- Albertus
- Kuenstler Script
- Bickham
- Mistral
- Plumero
- Bello
- Omnia
- Banco
- Choc
- Strangelove
- Old English
- Anglican Text
- American Text
- Manuskript Gotisch
- Comic Sans
- Trebuchet
