thank you for your effort creating and maintaining K-9 Mail so far!
But please give an option to switch to the old user interface. Before version 5.800, K-9 Mail was the only usable email client for smartphones. Should this era end now? Please do something about it. Please!
I’m absolutely the same opinion, the new GUI is terrible and unusable, e.g.
Why it is not longer possible to show subject and sender in one line ??
Why Noled doesn’t work with Version 5.800 ??
