I’m trying to find something and it’s not easy. I’m using claws now and I doesn’t seem to have dark mode.
Evolution should have it but my theme is set to ‘Adwaita-dark’ and evolution ignores it?
Thunderbird pissed me off by removing the tray icon…
I tried aerc but it didn’t connect to my mail server for some reason.
Any other decent client that does support dark mode?
Finally I forgave Thunderbird and went back to it. There's birdtray app available in packages that handles the tray icon notifications and works pretty well.
