K-9 is dead!
Even if there is still a “K-9 Mail forum” here, but on F-Droid K-9 can no longer be found and Google Playstore only shows the “new” app from Thunderbird.
As far as I have seen, the Thunderbird and K-9 Mail apps are exactly the same. So Thunderbird has finally taken over K-9 and in a few months no one will remember K-9 Mail… - What a pity!
Thunderbird is OK and I also use it on the PC, but the layout of K-9 was perfect for the smartphone. Why is a good layout being replaced by a bad one?
