Undaunted

Do you mean the CharaChorder? I thought about getting one in the past bit it looks like a super steep learn curve and I'm not sure if I'm willing to subject myself to it.

They dropped the Tidal integration and I'm still heartbroken. It was the best setup for music discovery. Haven't found a replacement yet.

There's Betterbird, though I don't know exactly what makes it better, except for still allowing to manually load external content in encrypted mails, which Thunderbird just removed for whatever stupid reason.
