Thunderbird 115 "Supernova" launches on Monday, July 10th! It's our first step towards a more modern, more beautiful, and more customizable Thunderbird experience.

We think you're going to love it, and we are endlessly grateful for all of your support throughout the years 💙

@thunderbird Know that this will be renowned as a regression in usability.
@ellenor2000 @thunderbird It might cause some headaches for some people (there definitely will be some very angry loud (minority)), but as far as I know, the most controversal UI changes (density, unified folders etc.) can be reverted in settings, because the Thunderbird team actually listens to user feedback (unlike some big companies).
@ymstnt @ellenor2000 Indeed. in fact, we're not even defaulting to the view you see in these screenshots. So it should still feel very comfortable to people who are used to the existing layouts.
@thunderbird
This might actually be an issue. People who love Thunderbird's current UI will slowly get annoyed. People who currently can't use it because it's scruffy looking, will not go into the settings to make it look modern. I believe you should create a"Thunderbird Neue" app that starts with a fresh UI, and don't alienate both groups.

@lobau @thunderbird @ellenor2000 Just adding a heads up about the new features (maybe even a walkthrough) would solve that imo.
