What more features does an email client need? It seems like a simple task that should be fully fleshed out by now.

if they can promise a not shit ui and more efficiency with large message operations im all for it. Those have been my complaints about thunderbird in the last year or two

Given the recent increase in momentum for Thunderbird development I was somewhat sceptical of it’s value, but that feature comparison hits a bunch of my Thunderbird bugbears.

I might migrate for a tray icon alone.
