I love current Thunderbird but it undeniably has its issues. Firstly, of course this is subjective, but its UI is starting to look dated. Lots of you are complaining about modern UIs, but I think the designs [0][1] look great and are much more readable than the current design, which looks straight out of Ubuntu 8.04.
Then there are some major UX issues, the most obvious one being the lack of conversation view, which is how pretty much everybody expects an email client to work in 2023. Supernova implementing that is reason enough to be excited about the release.
I can't wait to try it out - keep up the awesome work, team!
