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 @ymstnt @ellenor2000 Ah this is so great to hear! I will definitely try out all the new layout options, because it looks great! And if the density doesn't work for me, then I'll use the existing layout. Thanks for being considerate Thunderbird team!
