K9 is Thunderbird

Seems you didn’t even read my comment - but no, at least for the moment K-9 is not Thunderbird…

Been using K-9 for a time and tried Thunderbird - it feels kind of smoother and there are some visual overhauls but ended uninstalling it because it was hard for me to tell which mails were unread (and which ones not) in the main mail list while in dark mode. I guess I’m not the only one who felt that way and surely they will fix it but this also left me the sensation that there’s not much sense in switching to Thunderbird if you’re using K-9.
