One random guy's opinion (and a long-time K9 user):
Little UI design changes are NOT what you should be spending time/money on; they are a waste of effort given K9's already strong usability. I acknowledge it's your time/money but this does not make the app any more appealing. I know I sound like a broken record [1] but, at minimum, I believe Thunderbird could take quite a few users (who prefer privacy-focused apps) from both Google and Microsoft (not to mention 3rd-party apps [2] [3] [4]) by integrating functionality at the local level. This would be a considerable (IMO) differentiation in functionality. I will continue to use Outlook until there is a significant justification to switch to Thunderbird. And until "Thunderbird for Android" is significantly differentiated in functionality (i.e., ignoring UI), it will remain branded in my mind as K9.
