I just can’t find a decent email client that looks like it’s from the last 20 years. Geary and Evolution both appear to be pretty modern but something about using Gmail with a Yubikey just doesn’t work and neither of them will connect to my account. Both on Fedora and OpenSUSE. Thunderbird works but it’s so old fashioned and Betterbird doesn’t look much better. What’s everyone else using?
I like the 3 column layout on larger monitors. I’m forced to use Outlook at work, and the 3 column layout works well on my 32" monitors. And as bad as a lot of Microsoft stuff is, they do a decent job with Outlook. At home, using a 16" laptop, Thunderbird with the traditional layout is my favorite.
